Image plane intersection interference imaging spectroscopy is a kind of compact imaging spectrometer technology, which has characteristics of small volume and light weight, and is used for small satellite remote sensing mission or airborne photoelectric reconnaissance. Image plane intersection interference imaging spectroscopy was studied. The design scheme of angle shear beam splitter was given based on Mach-Zehnder composed of prisms. Work principle and design method were discussed in detail. The angle shear of beam splitter based on Mach-Zehnder was analyzed under certain spectrum resolution combined design example. At same time, object characteristics of image plane intersection interference imaging system was studied. Image plane intersection interference imaging spectroscopy technology was verified in experiment.
