| 摘 要： | 根据微光像增强器成像特性，设计了微光全景光学系统，采用反射式前组与透射式后组结构。重点阐述反射式前组的设计方法，并据此设计优化得到了性能优良的成像系统。该系统有效焦距2.43 mm，工作波段0.4 m～0.9 m，有效工作F数1.5，水平视场360，垂直视场30～100。设计结果表明，系统全视场f 畸变小于6%，调制传递函数在24 lp/mm处大于0.3，系统指标满足成像要求。

| Abstract: | According to the property of low-light-level (LLL) imaging system, the LLL panoramic imaging system was designed, which was made up of a reflection part and a transmission part. The basic theory for designing the reflection part was expounded, and according to the theory, a imaging system of good performance was designed and optimized. This system has a waveband of 0.4 m~ 0.9 m, an effective focal length of 2.43 mm, a working F-number of 1.5, and a field of view of 30～100. Simulation results show that in the entire field of view, the distortion is less than 6%, the value of the modulation transfer function (MTF) at 24 lp/mm is greater than 0.3. The system can meet the demands for imaging. |
