Non-scanning 3D laser radar system based on Geiger-Mode APD Array can obtain two-dimensional information and the distance information of the target simultaneously with a single pulse，and it has important applications in military and civil fields. Firstly，advantages of non-scanning 3D laser radar system and Geiger-Mode APD Array are introduced. Then the principle of APD device and 3D laser radar system based on Geiger-Mode APD Array are introduced，and the theoretical research and development status about laser radar system are summarized. Finally，development trend about non-scanning 3D laser radar system based on Geiger-Mode APD Array is concluded，the development trend in China is also given in this paper.
