- W2900754827 abstract "Star sensor is a high accuracy sensitive instrument for attitude determination, and the optical system is an essential part of the star sensor. According to the user requirements and CODE V patent library, the optical lens of a star sensor with large relative aperture and wide-spectrum range is optimized. The final design consists of 8 spherical lenses. The focal length is 50mm, the relative aperture is 1/1.35, the field of view is 7° × 7° (the diagonal field is 9.9°), and the spectral range is 500nm to 800nm. The design results show the optical lens has good performance. The distortion is less than 1%, the energy concentration is more than 80%, and the MTF of all fields of view is close to each other. The energy concentration of the spot diagram on the off-axis field of view and the on-axis field of view remains basically the same. The optical system meets modern design requirements for the star sensors." @default.
