Abstract

The Fourier Transform Imaging Spectrometer (FTIS) used for remote sensing has been developed rapidly in the past two decades. Most of the Temporarily Modulated FTIS and the Spatially Modulated FTIS include a beam splitter structure, such as Sagnac prism or double refraction crystal beam splitter. The material of the beam splitter which is optical glass, crystalline materials or plastic optical materials all have the transmission limitation, so the spectrum range would be limited; the transparent material also would cause the chromatic aberration. We presented an all-reflective optical structure based on the Fresnel double mirror interference structure that could overcome these two shortcomings. The three-mirror anastigmat (TMA) telescope is employed to realize all-reflective fore-optics, it has a compact structure, wide field of view (FOV) and competent modulation transfer function (MTF). An abaxial parabolic-cylindrical mirror has been designed to focus the interference fringes onto the plane focal array (FPA) which would increase the signal to noise ratio (SNR).
