I don't have problem with you different opinions. Everybody might have different opinions.
But it gets worse when you give a base theory and which is not compatible with the Law of Physics.
You're still arguing with the fact that you said LiDAR doesn't measure time.
I mean How can it measure the distance if time isn't measured ?
Now how can a dot of laser split into many dots ?
Didn't you read in school that light always goes straight while remaining the same medium ?
Like I said, You're clearly from Business Administration or Humanities.
I'm probably just wasting my time to make you understand hard thing when you've no clue about the easiest laws.

I mean where do you get these useless talk.
This is why I am talking about base knowledge.
Here in this website you'll get a image which was provided by Apple itself while introducing the face ID.
https://www.pocket-lint.com/phones/news/apple/142207-what-is-apple-face-id-and-how-does-it-work
Now another link. Both in these post it's clearly said and shown that 30k dots are projected. Nowhere it's said 1 dot is split into 30k dots. That's is just impossible in the law of physics.
https://www.cnet.com/how-to/the-iphone-and-ipads-face-id-tech-is-pretty-darn-cool-heres-how-it-works-and-how-to-use-it/
It's clearly proven that you're simply clueless. That's happen when you have no base knowledge and argue with someone on the basis of what a stupid website shares without understanding it well.
I'm not gonna waste my time further. it's clearly no use to argue with a guy who has no base knowledge.

You just read a a post about something and then reply about that.
This is why you comment has different meaning over time.
I called you a liar not because of one thing.
You denied that you told anything about fast lens.
That's a lie.
Now you gave a screenshot and didn't bother to read the line which I said just before couple of lines. And the way you mentioned it proved it that you didn't understand a thing what I said.
Because same answer.
You lack base knowledge.
Like I said Last time,
You should rejoin High School. Your physics knowledge is weak.
Light doesn't split in the middle. Whatever the post you read says I don't care. Unless there were that amount of beams initially there is no way it will split in the middle.
You're the one who said big light source isn't needed for high res sensor. Now you're trying to put that on me.
So, shouldn't I call you a liar ?

AnonD-754814, 24 Sep 2020Hello Mr. Liar.
Can I call you Liar ?
I mean It suits yo... moreI literally took a screenshot on purpose to avoid any misconceptions and make sure I didn't state an wrong informations about what you previously said, which is why on my previous comment I clearly said I was not sure what you said exactly, but not only I put a screenshot but I also put a link, how can you say I am a liar when I am literally quoting what you said with a literal screenshot ?
You actually don't understand how those work despite me explaining it to you, I don't have "theories", that's the difference between me and other peoples and why I often talk so surely about what I said, because I do my researches before posting, it isn't even me having knowledge or my opinion, it is literally hard written facts.
And facts are :
ToF = Time of flight, which mean anything using any phenomena going from point A to point B and allowing to measure from point B back to point A the time it took, it can be light or other forms of electromagnetic radiations like mmWaves, it can be sound, it can be many other things with this image as a PROOF :
https://www.sfxrescue.com/wp-content/uploads/2017/03/tera-ranger-comparison.png
LiDAR = "Laser imaging, Detection, And Ranging" AND "Light Detection And Ranging" (because it is NOT ALWAYS about lasers), it refer, literally the name say it all, to any method using light, either in general or as a laser to make out informations, from simple distance to, more commonly, depth map.
Depth Sensor = The name is also a no brainer here, a sensor that can detect depth.
A ToF can be a simple laser rangefinder, laser autofocus is a good example, it can also be LiDARs and other things. Not a theory, it is a FACT, and it is literally in the name.
LiDARs work on multiple ways with those two charts as a PROOF :
https://www.eetimes.com/wp-content/uploads/media-1304429-automotivelidarplayers-yole.jpg
https://www.knowmade.com/wp-content/uploads/edd/2018/05/Main-IP-players-involved-in-promising-LIDAR-technologies.jpg
It isn't the name of a specific technology but, like "vehicles", it is about a method, it can be a single laser as, seen here with this video as a PROOF :
https://www.youtube.com/watch?v=1lDO1UevAJI
It can be more complex implementations from a multiple dots or lines in which it is "Structured Light" technique, as seen here with this image as a PROOF :
Lines : https://www.azom.com/images/Article_Images/ImageForArticle_16003(2).jpg
Dots : https://www.rpcphotonics.com/wp-content/uploads/2018/01/3d-structured-light.jpg
And many other patterns.
There are more than just structured light as LiDAR can also use a grid of dots/lines but rather than computing the deformations of each to gather depth, it can use ToF on each of those to get their distance, there are other methods (like 3D Stereo who isn't a LiDAR) to gather depth informations :
https://community.arm.com/resized-image/__size/1040x0/__key/communityserver-blogs-components-weblogfiles/00-00-00-20-66/Depth-Sensors.png
Yes, Face ID use a SINGLE diode and split it into 30k dots as seen here :
https://mainguet.org/biometrics/types/fingerprint/apple/AppleX_sensors_TI2.jpg
It use what is called a VCSEL (Vertical-cavity surface-emitting laser) diode to emit the initial laser which is then diffracted using a DOE (Diffractive Optical Element) to create that many dots, which is exactly what I said, and what you failed to understand, once again.
Those aren't knowledge on physic, those are facts from patterns, retro engineering and technical spec sheets.
Yes, I do write big comments, because already with many details, there are peoples like you who still can't understand despite literally a detailed and simplified explanation, so how would you understand a complex and short explanation ?
They aren't conflicting, you just aren't able to understand them to beggin with and interpret things so wrong that you conclude I talk about different things, as in reality, things are super easy to understand :
It begin with a laser which pass through a filter who split it into many (30k) dots.
And you are the one who think we can't diffract a laser that way despite evidences of the contrary :
http://physicsopenlab.org/2017/08/29/laser-diffraction-grating/
I can't count the number of time I link reliable sources (like patents, scientific papers, article from scientific news, etc) and peoples just totally ignore them and pretend I am wrong and they are right while I literally only quote facts, and you are the king at that.
First link, I asked and learned from what the guy wrote.
Second link, I stated facts, regardless that you dislike it because it doesn't match with your beliefs, those are facts, not a theory.
I didn't talked about "12Mp laser beams".
I talked about 12Mp Flash LiDAR, which use either ONE widely unfocused or NO lasers (simple LED) as seen here :
https://www.researchgate.net/figure/LiDAR-vs-Flash-LiDAR-technologies-Courtesy-wwwfosternavnet_fig3_261333968
"I said 100 beams to give another example like if the laser beams size is big than 100 beams are more than enough."
Literally, this sentence isn't even proper English, "laser beams size is big than 100 beams are more than enough" mean absolutely nothing, it isn't a coherent sentence.
And it probably reflect your idea on the subject.
Still, 12Mp is the industry standard for many DSLR camera and only few years ago we started to see more than few reaching over 20Mp, many are still on the 12Mp region today as those resolution already give enough details, what matter is the improvement on quality those 12Mp image gave rather than the pure resolution.
I had many XMp things who had a crappy quality that would be far lesser than their supposed resolution by an order of magnitude, this is the perfect example of how resolution isn't everything, pixel loss have greatly reduced nowaday which is exactly why we got more sensors over 12Mp as we have pretty good 12Mp sensors, it wouldn't have make senses to have higher resolution if the quality didn't improved in the first place.
So regardless what you say, 12Mp is STILL the standard because it is already high enough, even downscalling it it still output a more than big enough resolution for most uses.

Can I call you Liar ?
I mean It suits you.
First of all ,
Lets talk about LiDAR.
That time when I talked with you(mostly argued) you clearly had stupid theories about ToF and LiDAR just like you have now about other stuff.
* Ignorantly you said LiDAR doesn't measure the time.
* And then said Apple's Laser split in the middle.
{your quote: the Apple's Face ID actually use a single initial laser that is then split into many others }
This is what you said that day. Now you're said it uses 30000 dots ?
Like I said before Your knowledge on Physics suc*s.
Also another problem with you is you write the comment to large and your different comment has different theory conflicting between them.
Now you're lying about what you said.
Good thing is I have very good memory.
Here are the two threads where you gave your stupid theories.

AnonD-754814, 24 Sep 2020So, Now you're just lying ?
I talked about 12 million... moreThere :
https://imgur.com/a/4970tGo
You said 100 laser were enough, as said, I didn't remembered what exactly you said, but I remember it was quite ridiculous.
Your 12Mp theory was also false anyway as the sensor always have greater resolution than the number of laser, plus that was also where I insisted that there is no need for multiple beams for Flash LiDAR and you persisted with talking about multiple lasers.
And who care about your opinion about my opinion then ?
Or your opinion on anything I said for that matter ? Yet you are still giving them, so, yeah...
12Mp low resolution ?
Dude, literally the two smartphone with the biggest resolution are the Sony Xperia XZ Premium and the Sony Xperia Z5 Premium, both with a 3840×2160 display.
3840×2160 = 8,294,400, or 8,3Mp.
Also, most DSLR makers and Google, Sony and Apple who are notorious for their high quality picture didn't got the memo that 12Mp wasn't enough apparently...
Because last time I checked, they used 12Mp main camera.
I don't remember exactlky, I was probably talking about the fact that larger sensors are notorious to have better light gathering capability than smaller ones and also that using a really big aperture focused down to a smaller sensor allow for a big pixel density, which I just found out a page confirming that btw :
https://clarkvision.com/articles/does.pixel.size.matter/index.html
I don't know exactly what I said, if you want to go through the comments yourself, here is the link :
https://www.gsmarena.com/newscomm-44758p2.php
I just know it was an eternity ago and I am a really quick learner, I know much more now, I was literally few days into understanding photography back then, one sure thing though, how might behave is quite logic and it seem pretty intuitive, knowledge or not, that you get higher photon density by concentrating a large aperture to a small sensor.

I talked about 12 million dots for 12MP camera. I said we need 12 million dots to use 12MP sensor.
And here you're saying I said no more than 2000 ? I was the one who said there isn't enough light source to use high res sensor.
Same opinion here.
People really don't give a damn about you useless theory. Like Samsung names their flagship S21 or S30, who cares about that naming ?
And Like I said, 12MP is low resolution for current high resolution display. But your stupid theory suggest it's good for main camera but not good for UW camera.
You tried to explain about and I already mentioned how that proved your knowledge.
And didn't you mentioned about using super wide aperture with big sensor in a comment with an anonymous guy ?

Smartphone users ... moreStill, computer have 3.5mm Jack, most motherboard even have 5 despite the popularity of USB headset for gaming.
There is also the fact that USB headsets have 3D sound effect and come with their own tiny motherboard while pro/music headset are mostly using 3.5mm Jack as they only need to be stereo.
My Corsair Void Pro for example, despite being plugged in USB is actually a Jack cable plugged into its small USB sound card and doesn't have any sound difference from any USB only headsets.

AnonD-754814, 24 Sep 2020Looks like you're smarter than the Engineers that Sams... moreActually, despite me explaining it multiple times in multiple ways, you completely failed each times to understand what I was talking about and you were starting to get into incredibly wrong theories that couldn't be even further from what I was saying.
You apparently can't understand a concept as simple as "pixels per degrees" and the relation between a increasing angle proportional to lower angular resolution.
I think everyone else can easily understand that, for the same sensor, if you get from a typical main camera angle up to an ultra-wide, you spread the pixels over a larger area, resulting in each objects in the scene being lower resolution.
The only thing I talked about was to necessity for "ultra-wide" to have higher resolution than the final binned (usually 12Mp) main camera so objects have close enough resolution between the two, and to make telephoto with higher resolution so on top of the optical zoom we can push a little further with the numeric zoom thanks to the higher resolution without loosing too much details.
You are the one who got totally way lost and talked about different things, I never once mentioned slow or fast lenses.
And your laser incomprehension, I literally linked Apple patent and you still think you are the one being right, you can't make this up...
You insisted on LiDAR requiring many lasers while I clearly explained and showed you that typically what happen is those lasers are resulting from a single one being diffracted.
You insisted on saying that something like 2000 laser is the maximum or something like that, I clearly showed you examples disproving it, a 2 minute research quickly reveal that the Face ID structured light dot projector use 30,000 dots.
And I insisted on higher resolution using LiDAR tech that DON'T rely on a grid of lasers but either a single LED or a single laser which is widen up (unzoomed) to cover a wide area, a tech called Flash LiDAR, and you still insisted on laser numbers and totally failed to understand that there are MANY different types of LiDAR.
So, sorry, but I clearly won't personally consider what you say, and I never said I was most clever than those Engineers who do their job at making what they are asked to, I just talk about idea that the marketing department who insist on re-using again and again the same things without changing or improving them simply failed to come up with.
