大相对口径大线视场光学系统的设计
Design of the Optical System with Large Relative Aperture and Large Linear Field of View
文章论述了用于红外远距离探测的光学应是全反射式的大相对口径、大视场的离轴非球面系统。给出了一个通光口径为Φ600mm，相对口径1:1.67，线视场为±5°的设计结果。
In this paper following discussion the author concluded that the optical system for IR detecting in the distance should be an total reflecting off-axis aspheric system with large relative aperture and large field of view. A system with diameter φ600 mm, f=1000 mm, and linear field of view ± 5° was designed.
