CA 2180692

A laser range finder receiver (16) for detecting a return pulse and providing an output signal indicative thereof and a single-chip microcontroller (13) for controlling receiver operation and, in particular, for automatically recalibrating the receiver (16). The receiver (16) is responsive to up and downcurrent control signals (IUP, IDN) from the microcontroller (13) to adjust the bias of an APD photodetector (315). An offset voltage and receiver false alarm rateare monitored with no light on the photodetector (315) while a calibration voltage (VVAL) is adjusted to recalibrate the receiver (16). The microcontroller (13) further monitors photodetector temperature via a temperature sensor (319), and can perform APD bias adjustment and receiver recalibration in response to temperature changes, providing operation over a wide temperature range).
