Nit: Projected patterns are structured light, not time-of-flight. As far as I’m aware (would love to be wrong!) you can’t do ToF with a traditional CCD or CMOS sensor and resolution is invariably woeful.
Hm, last time I checked I thought the sensors were individual diodes but it looks like you're right, and 'flash LIDAR' cameras do use some funky kind of CCD. Still relatively low resolution but good to know, thanks!
