摘要：

The alignment method of a fast catadioptric optical module with very large field of view is presented in this paper. The module is made of three aspheric optical components: a primary mirror, a secondary mirror and a field lens. To achieve the 22.6 degrees field of view, the secondary mirror makes a large obscuration requiring an F/0.75 working f-number to achieve the effective F/1.05. The catadioptric optical module was integrated with the IRXCAM-640 uncooled camera module made by INO. System spatial resolution is improved with the use of a 4-position microscan mechanism.
