摘　　要：介绍了基于同心结构的凸面光栅成像光谱仪的研究背景、设计方案和结构特点,综述了凸面光栅同心结构成像光谱仪在国内外目前主要的五种结构类型,包括Offner型、非共面型、折反射型、+1级衍射型、自由曲面型。总结了五种结构类型的优点和缺点对研发新一代具有高成像质量、高分辨率、高衍射效率、大相对孔径长狭缝、宽波长范围的轻小型成像光谱仪具有重要的指导意义。The research background,design scheme,and structure characteristics of a convex grating imaging spectrometer based on a concentric structure are introduced. Five main configuration types of concentric imaging spectrometers with a convex grating at home and abroad are reviewed,including Offner type,off-plane type, catadioptric type, +1 st order diffraction type, and freeform surface type. The advantages and disadvantages of these five configuration types are summarized. It has important guiding significance for the research and development of a new generation of light and small imaging spectrometers with high imaging quality,high resolution,high diffraction efficiency,large relative aperture,long slit,and wide wavelength range.
