Abstract

The invention discloses a photoelectric signal amplification device for a laser range finder. An input optical signal is converted into an electric signal through the photoelectric conversion loop, and a high-signal-to-noise-ratio electric signal is output to the pre-stage amplification loop for pre-stage amplification of the electric signal. The electric signal output by the pre-stage amplification loop is further amplified through the second-stage amplification loop. The circuit is simple in structure, the photoelectric signal amplification function with the high signal-to-noise ratio is achieved, noise is prevented from being introduced into the circuit, meanwhile, the temperature drift problem caused by application of discrete devices is avoided, and the stability of the circuit is further improved.
