摘要

In view that the sun is a main stray light source for space-based camera with wide filed as high-intensity light, the influence on the image quality of the camera was studied. Through the design of the camera's lens hood, the number of stray lights scattering on the surface of the lens is reduced. Then the stray light which can reach the detector is diminished. Compare the image quality of the flying surveillance camera with which before the lens hood designed, the maximum value of PST(θ) outside the critical angle 55°was reduced to 1.1099×10-9. Stray light was significantly inhibited, and the image quality was effectively improved.
