Optical Design Of Spectral Imaging System

Hyperspectral imaging technology is widely used in military and civilian applications because of the rich spatial and spectral information it provides about the scene being imaged in a spectral resolution of a magnitude of nanometr. Fourier Transform Spectroscopy is a technology which to get spectrum from inference picture by using the fourier transform. The development of Fourier Transform Spectroscopy,the research and applying situation in remote sensing field are reviewed and summarized in paper. The essential theory, basic configuration and advantage of Imaging Fourier Transform Spectrometer are analyzed. The imaging theory and factor of optical path’s design of triangle common-path maging Fourier Transform Spectrometer is especially discussed. Parameters of the design such as the factor of telescopic system,the parameters of the prism and the slit width etc. are designed. The using the sofware ZEMAX,t he optical path is designed in computer and the aberration is analyzed. Finally,the imaging quality reached the design target.
