Abstract

The invention discloses a receiving circuit of a laser range finder. The receiving circuit comprises a first power supply, a second power supply, first to tenth capacitors, first to seventeenth resistors, first to fourth triodes, first to fourth diodes, a first inductor and a second inductor. The receiving circuit is simple in structure, low in cost and high in amplification factor which is about 12,000 times, the bandwidth ranges from 0.5 MHz to 14 MHz, the output impedance is reduced, the transmission coefficient for low load impedance is increased, the directivity is high, energy consumption is low, and the effective range is wider.

Description

technical field [0001] The invention relates to a receiving circuit, in particular to a receiving circuit of a laser range finder. Background technique [0002] A laser range finder is a distance measuring instrument that uses laser pulses or continuous wave laser beams to measure the distance of a target. A laser range finder generally consists of three parts: a laser transmitter, a laser receiver and a power supply. The laser receiver is composed of receiving optical system, photodetector and amplifier, receiving circuit and counting display. The function of the device is to receive the laser pulse echo diffusely reflected from the target and calculate and display the target distance. Today's laser receiving circuit structure is too complicated, and the cost performance is too low, which greatly limits the popularization of laser testers. Contents of the invention [0003] The object of the present invention is to provide a simple and effective receiving circuit of a l...
