A high image quality light-small remote sensing camera design conception is proposed to satisfy the requirement of the high resolution, light weight and high image quality commercial applications. Adopting three mirrors reflection coaxial optical system, combined with light weight, high stable opto-mechanical and TDICMOS imaging circuits, is achieving the design result of 80Kg weight and 150watt power consumption. and acquires images through push-broom mode. To achieve the high SNR, the Precision Loop Heat Pipe (LHP) is adopted to keep the TDICMOS sensor operating under stable and low temperature, and the fixed pattern noise is statistically analyzed in the lab and then removed by onboard processor in real time. For MTF, Modulation Transfer Function Compensation (MTFC) algorithm is used to improve the final MTF value. The interior orientation elements stability is achieved by dedicated design of reflection mirror and its supporting structure, and indirect high precision thermal control for opto-mechanical structure. The star sensor brackets are directly mounted on the primary camera structures, meanwhile, the thermal and stiffness performance of which is specially designed to keep the exterior orientation elements stable. The final design gives the result of the 48dB for SNR, 0.15 for static MTF and high geometrical stability.
