For an encyclopedic article, you have to do a lot of guessing here. https://en.wikipedia.org/wiki/Intel_RealSense The third party sensor there, the article makes it seem it is a single array, but there are enough pixels for two arrays. And like the human eye, as long as the collecting optics are separated by enough, you get some extract-able depth information. Some of the cameras Intel makes, have an IR projector, and the "ordinary" sensor arrays in the Intel camera see out far enough, to pick up the IR pattern. https://dev.intelrealsense.com/docs/projectors For Windows Hello, this additional information (collect depth info from projected IR onto a 3D object), was supposed to make it harder to fake an authenticating face. But I think hackers managed to defeat Windows Hello anyway. One of the things with these cameras, is they don't always have a fleet of "ready applications" for end users. They can include an SDK and you write your own software. One of the things on the SDK for the Intel camera, is you can stick the head of a statue on a turntable, and rotate the object slowly, and the Intel RealSense camera will give you a file suitable for 3D printing. And you can make a "copy" of the object you just scanned (out of filament). One software person working with the Intel kit, called what the Intel camera was sending a "point cloud", and that's also a terminology used with LIDAR systems for automobiles. The LIDAR industry still exists, but they've been keeping a low profile :-/ https://cleantechnica.com/2021/03/12/lidar-may-be-harmful-to-people-cameras/ Paul
