AB - With the complex and changeable space environment, in order to realize wide-area space debris detection, a super wide-angle space-based detection camera optical system is proposed. By discussing the application requirements of the space-based optical detection system, the technical index of the system is determined, and the detection of stars with luminance no less than magnitude 4.5 is realized. In the design process, the influence of stray light formed by strong light source in the field of view is effectively controlled, and the performance of both bright and dark targets can be observed at the same time. The pixel resolution of the optical system is 1750×1750, the focal length is 12.9 mm, the entrance pupil diameter is 6.5 mm, and the field of view is 91.5°×91.5°. In the spectrum range of 450nm~900 nm and the color temperature range of 2600K~9800 K, the distortion in the whole field of view is better than 25%. The centroid deviation between different color temperatures is better than 1.5μm, and the energy concentration of the dispersion spot in 2×2 pixels is between 75% and 90%, and that in 3×3 pixels is not less than 90%. Considering the influence of external space environment temperature, the passive optical anthermalization design can adapt to the operating temperature of -40℃~+55℃.
