Abstract :
A high-speed 3D range finder uses current-mode subtraction, a row-parallel embedded binary search tree and address encoding, and a mask circuit to achieve 14.4k-range-maps/s, and the maximum and the standard deviation of range error of 0.997mm and 0.258mm, respectively, at a target distance of 400mm.
