The Stray Light Analysis for AST3-3

Haiping Lu, Kaiyuan Zhang, Xiangyan Yuan

Antarctic Dome A is considered to be the most outstanding astronomical photometry and observation station sites on earth, particularly in the infrared. To take full advantage of the unique advantages for astronomical observation , we propose adding an Infrared Survey Camera on antarctic survey telescope AST3-3. Suppressing the stray light is important for astronomical telescope. We analysis the point source transmittance(PST) ,the effect of suppressing the moon light and the self-radiation.
