ST Micro 2018 Capital Markets Day was used to present the company focus on all types of 3D imaging: SPAD-based FlightSense, structured light (probably Apple Face ID IR sensor), and also indirect ToF:
missing all the important stuff, like what is the quality and characteristics of their depth maps vs various targets. What are the intended and targeted use cases ? These are what should be thought of primarily when comparing 3D sensors.
Structured light and ToF both belong to active 3D image. What cause ToF consume more power than structured light? It's the first time I learned that choice of sturctured light results from power consumption. So I hope to learn more about it.
These are just presentation with no real product, the keyword here is "technology focus", they are selling vaporware! no chip teardown indicate product on 40nm
Interesting that they use AMS as acronym as it is the name of their competitor.

ReplyDeleteFor face detection like face ID in iPhone X, is ToF not a good choice? Why?
ReplyDeletevery high power consumption

DeleteIn ITOF transfer gates are very fast driven. In structure light the sensor is standard speed
