For the realization of target detection and monitoring of a wide range with the unmanned aerial vehicle(UAV),an UAVbased reconnaissance and surveillance system was proposed.The main optical system was consisted of visible camera with narrow field of view(FOV),mid-wave infrared camera(MWIR)and long-wave infrared camera(LWIR).The aperture was shared and the spectrum was disparted in the terminal.The diameter of primary mirror was 170mm.The focal length was 880mm and field of view was 0.86?for visible camera with narrow FOV,the focal length was 880mm and field of view was 0.8?for MWIR camera,the focal length was 220mm and field of view was 3.2?for LWIR camera.Considering the influence of temperature on the imaging quality,a kind of material with good thermal property was used as mirror substrate.The athermalization method was introduced to realize a high image quality in a wide temperature range of-40℃~+65℃.Zoom optical system was adopted in the visible camera with middle FOV and wide FOV,the view of it was 3.4?~34? The operating distance of laser channel was designed to 20km.The results of the design indicated that this set of optical system could be used for ground target detection and monitoring of a wide range,met users requirement.
