微光全景光学系统设计

Design of low-light-level panoramic imaging system

  • 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.
