Because of high resolution and fast speed imaging of ladar using multi-element array detecting, it is becoming research hotspot, and coming to engineering gradually. Based on this background, an overview of multi-element array detecting technology of ladar is given. First, the present detecting models for target are compared,the characteristics and developing orientation of ladar detecting are briefly described. The progress of array detecting technology of laser at home and aboard is introduced, and the system composition and working principle of multi-element array detecting of ladar are given. The key technologies are analyzed, such as optical technology of multi-element array detecting, high sensitive detecting and receiving technology of multiplex signal, laser image processing and software design technology etc.. The existing difficulties of developing multi-element array detecting are discussed. Finally, the application prospect is predicted based on the analysis of state of the art of APD array.
