为实现高光谱成像系统小型化、轻量化和高成像质量的要求，并使全工作波段具有更高的光学效率，提出以Féry棱镜组合作为分光元件的Dyson高光谱成像仪系统，系统中引入消色差棱镜组合以减小光谱的非线性色散，使棱镜系统色散的线性度达到较高。结果表明，可见近红外（VNIR）光谱通道的光学调制传递函数（MTF）达到0.9以上，光谱分辨率为4.2～6.8 nm。短波红外（SWIR）光谱通道的MTF达到0.73～0.87，光谱分辨率为6.4～12.5 nm。通过消色差Féry棱镜组合的设计，该光学成像系统两个光谱通道内的相对谱线弯曲均小于0.05%，色畸变小于0.13%。

In order to achieve the requirements of miniaturization, light weight, high image quality of the hyperspectral imaging system, and improve the optical efficiency for the whole spectral range, the Dyson hyperspectral imaging system with achromatized Féry prism is presented. To decrease the nonlinear dispersion of spectrum, the achromatized prisms are introduced into the system. The optical modulation transfer function (MTF) for visible-near infrared (VNIR) spectral channel is higher than 0.9, and the spectral resolution is about 4.2～6.8 nm. The MTF for short-wave infrared (SWIR) spectral channel is 0.73～0.87, and the spectral resolution is about 6.4～12.5 nm. The achromatized Féry prisms correct the spectral-line bending and color distortion of the two hyperspectral imaging systems. Optical simulation shows that the distortion is less than 0.13% and the spectral bend is less than 0.05%.
