Compared with general method of range finder, the laser range finder has a lot of advantages such as easy to operate, available day and night, high precision, etc and has been widely used. Firstly, the principle of the laser range finding telescope was introduced. Secondly, the digital signal processing methods of laser echo such as sampling, filtering and correlation detection were analyzed. Experiments show that this method can pick up the signal from noise quickly and effectively.
