| Abstract: | With changing time and external scenes and based on a dynamic imaging process, the stray light
layer images are simulated by computing the stray light with the Monte Carlo method. Compared with
traditional methods for stray light analyses, the proposed method can simulate two-dimensional stray light
distribution images, and directly compare with remote-sensing images obtained by a space optical system.
Based on the experiments on the simulation images of stray light for FY-2 meteorological satellite at midnight,
the simulation results show that the method can evaluate the mechanism, path and suppression of the stray
light effectively. |
