Abstract
In the omni-directional optical system used for real-time surveillance, we established the theory of basic optical design for a two-reflector catadioptric omni-directional optical system which has a convex primary mirror and a plane secondary mirror as its reflection imaging part. We also established an algorithm and programmed to analyze the variables of the theory. By using this method, the key optical elements related to the primary and secondary mirrors in the system can be simply and easily designed based on the optical system variables such as radius of curvature for the primary mirror and position of the secondary mirror, and location and radius of entrance pupil of the refractive imaging optics. And we achieved readily and successfully an infrared omni-directional optical system for night vision and surveillance of defense and safety by using the basic design theory.
