Abstract
In this paper, a new structure of infrared imaging system consisted of a diffractive primary mirror, sub-mirror and emendation lenses are proposed. The focal plane field distribution of the imaging system is calculated to show the imaging performance, and the imaging performance is optimized by using ray tracing method and Stratton-Chu diffractive integral formula. The system has a better performance over the field of view ±2°.
