摘要	To get the atmosphere images and data information with high spatio-temporal coverages and high vertical resolution, an opto-mechanical structure for the imager with two field of views and multiple channels was designed based on the environmental adaptability and accuracy requirements. In consideration of detection and position accuracy, a nadir and limb multiple-azimuth observation model was used in the optical system and corresponding mechanical structure. A flexible system was taken to allow the imager to operate at a temperature range of 45 normally. Duo to a larger temperature range, the precision positioning and cooling system for a CCD bare chip was constructed. To verify the feasibility of the opto-mechanical structure, the performance of the optical system in the imager was tested. The experimental results indicate that the spatial resolutions of the three optical channels are all better than 4 km under boundary temperature, which shows the imager can be used in limb and nadir detections. The imager shows its mass is 8.3 kg, the first order frequency is greater than 100 Hz, and the max stress is 52.5 MPa. The designed opto-mechanical structure is reasonable and compact, the opto-mechanical structure satisfies the requirements of strength, stiffness and target detection, and it is suitable for the space remote sensing. 2015, SCIENCE PRESS.
