Abstract

The time-of-flight distance measurement is based on measuring the time interval between the transmitted (star!) and received (stop) light pulses. The light transmitter can be a laser diode and the light receiver, a PIN diode or an A PD. Both the variation of the reflectance of the object and the distance between the receiver and the object cause variations in the amplitude of the received light pulse. These variations induce timing walk on the stop pulse detection if it is based on a simple constant threshold detection.
