Paper Abstract

Development process of laser rangefinder is introduced briefly in this paper. Working principle of laser rangefinder and ranging equation is also discussed. Relationship between signal to noise ratio (SNR) and ranging capacity is analyzed. By using spectral filtering, spatial filtering, and cumulative technique, ranging distance can be improved. The maximum of ranging distance can reach 1000m in good weather conditions. Ranging accuracy of laser rangefinder is decided by forefront of laser pulse, response time of APD and bandwidth of amplifier. It is about 1m.
