Abstract

Abstract:

We design a receiving circuit for a pulse laser rangefinder with the control over bias voltage of APD and amplifier gain to improve its range accuracy. Simulation results show that the circuit can receive greater echo power of dynamic range of 80 dB and implement output voltage of 0.5~2 V and valid bandwidth of 58 MHz. Test results demonstrate that the design is feasible.

Key words: pulse laser rangefinder, receiving circuit, wide dynamic range echo power, high speed pulse
