Abstract
A light receiving circuit of a laser range finder comprises a photo-sensitive element, a conversion resistance amplifying loop, a main amplification loop, and a one shot circuit. The photo-sensitive element converts a light signal into a current signal. The conversion resistance amplifying loop is connected with the photo-sensitive element for converting the current signal into a voltage signal. The main amplification loop is connected with the conversion resistance amplifying loop for amplifying the voltage signal. The one shot loop is connected with the main amplification loop for shaping the voltage signal into a digital signal by which the range-finding computation is accomplished by the laser range finder.
