What is ToF (time of flight)?
Measuring distance from the time light takes to travel to an object and back. ToF sensors are used in face recognition, robotics and automotive LiDAR.

A ToF sensor measures the round-trip time of light reflected from an object and computes distance = speed of light × time ÷ 2.
What is the measurement principle of a ToF (time-of-flight)…To improve near-infrared response for face authentication and ToF, structures that texture the surface to scatter light obliquely and lengthen its path within the pixel are used.
