Image Plane Interference Imaging Spectroscopy Study

The Imaging spectrometry is a high technology which can obtain the two-dimensional information and spectral information of the traget, is an integral part of the solution of remote sensing of the earth observing system, and therefore become a focusing developmented remote sensing technical over the years. The image plane interferometric imaging spectrometer in my thesis with its high energy efficiency and simple structure and stability become a hot research instrument. This paper main focuses on the structure of the spectral imager design, shear beam systematic error with the interference information extraction and recovery spectrum algorithm. First, derivate the spectral imager field of view angle, the front optical system exit pupil position and pupil diameter with shear beam system volume relationship to laid the theoretical basis for the follow-up to build the prototype portability and miniaturization; Second, analysis the influence of first and second parallel error to spectral resolution, the distribution and contrast of fringe patterns to determine the error tolerance to provide theoretical guarantees for the performance of the instrument; Third, build principle prototype under the connection between spectral imaging instrument field of view angle, the front optical system exit pupil position, the exit pupil and shear beam splitter system volume,do indoor and outdoor experiments to obtain the original interference detection image; finally study the original interference image information extraction method, and spectral recovery efforts. Recover the probe target spectral graph, and achieved satisfactory results.
