Full Definition & Technical Explanation
ToF (time-of-flight) / LiDAR sensors measure how long light takes to return, building a depth map. See Depth sensor (TOF 3D): Yes. It sharpens portrait separation and speeds autofocus in the dark.
Apple calls its version LiDAR on Pro models. It also powers AR measuring apps.
