Alignment of Off-axis Three-mirror Multispectral Camera

Abstract

The alignment of off-axis three-mirror system is difficult in the research and development of remote sensor.In this paper,an off-axis three-mirror multispectral camera was developed with the help of many instruments and computer aided alignment software.The final test results showed that the static MTF of each spectrum in library was more than 0.24(at Nyquist frequency),which could well meet the requirement.
