Abstract
According to the technical requirements of multi-spectral camera, using telecentric of TMA system, to meet the low distortion request of surveying and mapping. Considering factors, such as processing, assembly and adjustment, spherical surface shape is designed for the second mirror to ensure the fabrication reliability. The image quality is excellent, the relative distortion is less than 0.012%, and full field MTF of each spectral at the Nyquist frequency is better than 0.75. The static MTF test result of the multi-spectral camera is more than 0.2, and it meets the surveying and mapping requirements.
