B. Ravindra scite author profile

A stationary, compact, spatially modulated Fourier Transform spectro-radiometer based on triangular, common path Sagnac interferometer has been developed using linear CCD array detector for sampling the interferogram fringe pattern. The Optics and system configuration are described and the preliminary results are given. The system modification for making a push-broom Imaging hyper spectral system suitable for airborn/spaceborn measurements has been discussed.
