Abstract

This paper introduces some optic-electronic detectors which are applied in Satellite Laser Ranging (SLR) system, such as XP2233B, GDB49, MCP (Micro Channel Plate)-PMT (Photomultiplier Tube), SPAD (Single Photon Avalanche Diode), etc. The comparisons of these detector's performance and main parameters are given. With the improvement of the parameters, the laser range precision and system stability are improved. The focus is on the widely used detectors-MCP-PMT and C-SPAD. After comparing the advantage and disadvantage of the two kinds of detectors, the range precision and system stability improvement are presented based on the detectors.
