摘要：

An advanced detection system, based on mercury cadmium telluride avalanche photodiodes array, was implemented within a 2-mu m lidar. Detection system characterization was conducted for performance evaluation including settling time, noise -equivalent-power (NEP) and dynamic range. Results indicated an average NEP of 1.4 fAV/Hz(1/2) per pixel. Lidar range resolved profiling demonstrated the dynamic range capability by measuring near-field aerosol scattering and farfield clouds reflection simultaneously.
