A coherent-dispersion stereo-imaging spectrometer is presented, which combines three-view stereo imaging, interferometric spectroscopy and dispersive spectroscopy. Three area-array detectors record three spectral images of each scene unit from three views. For each of the three views, each scene unit is imaged on a given column of one area-array detector, and different wavelengths are dispersed across different rows of that column. For each scene unit, multiple interferograms are simultaneously generated at each view, each interferogram covering a separate wavelength range and located in a separate pixel. The orthographic view image is used to create a two-dimensional orthophoto image. The front view and back view images are used to reconstruct the three-dimensional stereoscopic image. Preliminary theoretical calculations are given. The instrument is a unique concept to obtain three-dimensional spatial information and one-dimensional spectral information while achieving high spectral resolution measurement of an ultraviolet-visible broadband spectral range (e.g., 0.05 nm at 450 nm together with 0.1 nm at 700 nm). It will be suitable for ultraviolet-visible hyperspectral remote sensing.
本文介绍了一种相干色散立体成像光谱仪，它结合了三视立体成像、干涉光谱和色散光谱技术。三个面阵探测器从三个视角记录每个场景单元的三个光谱图像。对于三个视角中的每一个，每个场景单元成像在一个面阵探测器的给定列上，不同波长分散在该列的不同行上。对于每个场景单元，在每个视角同时生成多个干涉图，每个干涉图覆盖一个单独的波长范围并位于一个单独的像素中。正视图图像用于创建二维正射影像。前视图和后视图图像用于重建三维立体图像。给出了初步的理论计算。该仪器是一种独特的概念，可在实现紫外可见宽带光谱范围（例如，450nm处为0.05nm，700nm处为0.1nm）的高光谱分辨率测量的同时，获取三维空间信息和一维光谱信息。它将适用于紫外可见高光谱遥感。
