The method of combining outdoor extinction method and indoor timing gain coefficient ratio is proposed to measure the maximum range of laser range finder. The method of combining precision optoelectronic delay and laser echo simulation technology is used to realize the measurement range, Ranging accuracy, gating range and accuracy, distance resolution and other key performance parameters of the indoor simulation test. The principle of the test is discussed, and the experimental data of laser range finder is analyzed. The experimental results show that the proposed method can be used to accurately test several main performance parameters of pulse laser range finder and provide reliable measurement data for objectively evaluating the performance of laser range finder.
