Abstract :
This paper describes the composition and working principle of lasermeter system , and analyze the reasons for Measurements Become larger when the background Luminance Increasing, which not reach the reasons ranging accuracy.Through the Calculation of optical power and Description of APD characteristics ,it proposued an optical and electronic methods of APD receiver circuit , reduce the I-V Conversion resistor and increase in amplifier compensation unit to achieve under normal lighting conditions ranging accuracy to meet the requirements.
