摘要
设计了一种使用固定校正器进行像差校正的共型光学系统,固定校正器采用大口径非球面透镜,对各子跟踪场的像差进行了严格校正。位于固定校正器后的成像系统进行回转跟踪时,搜索角度最大可达±80°,成像质量较好,且不会产生半球形整流罩光学系统在大角度搜索时容易出现的挡光现象。光学系统光阑与探测器冷屏重合,冷光阑效率达到100%。
A conformal optical system with fixed corrector to compensate aberrations is designed.The fixed corrector is a large diameter aspheric lens,which can correct aberrations in each search-field,and the max search angle reaches ±80° as the imaging system behind the corrector rotating.The system achieves high image quality with no light blocked which usually happens in traditional semi-spherical dome optical systems during large angle searching.The cold stop efficiency achieved 100%.
