Paper Abstract

A laser power control circuit of discrete values in time and in magnitude is advantageous in order to increase the achievable measurement rate of PSD-based triangulation sensors. The exponential behavior of this power control circuit causes a very fast adaptation of the transmitted laser power into the desired range while the tendency to oscillate is decreased by the pre-defined time steps.
