提出了一种镜面角度校正方法，用于消除成像光谱分析(IMS)中的光瞳平面变形和亚视场图像晕影。解决了图像映射器上的两轴光反射问题，并给出了严格的解析解。细胞荧光成像实验表明，使用角度校正的图像映射器，获取的光谱通道的图像质量比以前的IMS图像有了显著的提高。所提出的数学模型也可用于解决带有主动光学反射镜的仪器的一般两轴波控问题。
A mirror facet’s angle correction approach is presented for eliminating pupil plane distortions and sub-field image vignetting in the image mapping spectrometry (IMS). The two-axis light reflection problem on the image mapper is solved and a rigorous analytical solution is provided. The cellular fluorescence imaging experiment demonstrates that, with an angle-corrected image mapper, the acquired image quality of spectral channels has been significantly improved compared to previous IMS images. The proposed mathematical model can also be used in solving general two-axis beam steering problems for instruments with active optical mirrors.
