Abstract

A new lightweight infrared multi-spectral camera is developed. The camera is designed for near-space remote sensing. The camera is 13.6kg, and the angle resolution is 0.4mrad. It includes a middle wave (MW) channel (3.7μm~4.8μm) and a long wave (LW) channel (8μm~12μm). The optical system adopts a refract system, a dichroic beam-splitter is utilized to separate LM from MW. The MW/LW channel focus is 62.5mm, and the optical field of view is 14.36°×10.87°. The two channels all have five spectral bands. Filter wheel assemblies are used to split the in-coming MW and LW radiant flux into 5 spectral bands. The detectors of the two channel all have 640×512 pixels, and the pixel size is 25μm. The working temperature of MW detector is 80K, and LW detector is 60K. The two channels could image simultaneously. This camera has been tested in the low temperature and low pressure environmental test chambers. It also passes the random vibration tests. The camera has got 5 flights missions, and each mission is about 3~4 hours. Lots of good quality images are obtained during the flying missions.
