摘　　要：舰载机降落着舰时,有时需要用到光学着舰助降系统。本光源模拟器采用卤钨灯光源,紧贴卤钨灯光源加入光学均匀器,然后依据光源的出射光束分布情况加入光束整形锥腔,再依据光源视场角的要求,在一定距离处加入柱面阵列光学系统,在光学柱面阵列系统后加入光学滤光器和光学衰减器就形成了光学助降光源模拟器。本光源模拟器具备红、绿、黄三色光谱,水平视场达到30°,竖直视场达到20°,光强大于10 000cd,光源均匀性优于8%,光强可调。When the carrier aircrafts land on the ship, carrier optical landing aid system is re- quired on occasion. The lamp simulator used halogen tungsten light as light source, and a light uniformizer was added beside the light source. Then the beam shaping conical cavity was added according to the distribution of outgoing beam of light source. According to the demand of field angle, a cylinder array optical system was added at a certain distance. Then optical filter and optical attenuator were added at the exit pupil of the simulator. The lamp simulator had red, yellow, green spectrum, the horizontal field angle was 30 degree, the vertical field angle was 20 degree, the light intensity was over 10 000 cd, than 8%, and the light intensity was adjustable. the uniformity of the lamp-house was better
