In this paper we present a new hyperspectral imager based on a Fabry-Perot interferometer with low reflectivity dielectric mirrors. This set-up has been validated by measuring hypercubes of scenes containing emitting bodies and reflective surfaces in the visible region and compared with success with reference spectra. The system is based on dielectric mirrors which, with respect to similar systems based on metallic mirrors, have lower losses at lower cost and are available off-the-shelf. The spectra calculation is carried out with a Fourier transform based algorithm which takes into account the not negligible dispersion of the mirrors.
在本文中，我们展示了一种基于法布里-珀罗干涉仪且带有低反射率介质镜的新型高光谱成像仪。通过测量包含可见光区域发射体和反射表面的场景的超立方体，该装置已得到验证，并与参考光谱成功进行了比较。该系统基于介质镜，与基于金属镜的类似系统相比，其损耗更低、成本更低且可现货供应。光谱计算是使用基于傅里叶变换的算法进行的，该算法考虑了镜子不可忽略的色散。
