Abstract

According to the technical features and requirements of the television imaging system for tracking and measuring, we designed a TV system with focal length of 2800mm, F/11.7 and 2ω(FOV) of 14.2′. The system is compact and easy to fabricate and align, with good image quality. Meanwhile, we performed stray light analysis with ASAP optical software, described stray light suppression techniques used in the TV for tracking and measuring, proposed a method to determine optical properties of the system components and parameters of the scattering model reasonably. We calculated the PST curve of the system for incident angle from -45° to 45°. The results show that when the off-axis angle is larger than the critical incident angle of the sun, PST value is less than 10^-8.
