为了获得消像差Offner成像光谱仪，以三镜系统为基础综述了Offner成像光谱仪的各种消像差方法，介绍了由两块不同曲率半径凹面镜与凸面光栅构成的Offner成像光谱仪和狭缝与刻槽成不同方向的Offner成像光谱仪的消像差方法，并得到面内结构及正交结构两种成像光谱仪结构，其中正交结构在消像差方面更具优势，为获得高质量Offner成像光谱仪提供了理论基础。
為瞭穫得消像差Offner成像光譜儀，以三鏡繫統為基礎綜述瞭Offner成像光譜儀的各種消像差方法，介紹瞭由兩塊不同麯率半徑凹麵鏡與凸麵光柵構成的Offner成像光譜儀和狹縫與刻槽成不同方嚮的Offner成像光譜儀的消像差方法，併得到麵內結構及正交結構兩種成像光譜儀結構，其中正交結構在消像差方麵更具優勢，為穫得高質量Offner成像光譜儀提供瞭理論基礎。
