Abstract

A range sensor based on a laser diode has been developed. The laser diode transmitter and avalanche photodiode receiver are housed adjacently. The laser current monitor generates a 'start' pulse while the receiver generates a 'stop' pulse. The two pulses are input to a Schmitt trigger, monostable multivibrator, inverter and D flip-flop. The flip-flop output pulse train starts and stops a binary counter. The counter output is latched and displayed, giving the range in meters. The paper presents the results of the experiment, giving the flip-flop output pulse width versus the range to a mirror reflecting back the laser diode pulse.
