Paper Abstract

To avoid the drawbacks of conventional Fourier transform spectrometer (CFTS) based on the Michelson interferometer which needs a scanning system to acquire the interferogram in the temporal domain, the static Fourier transform (StFT) spectrometer has been developed. A new static Fourier-transform imaging spectrometer based on the Sagnac polariscope is proposed. The novelty of this work comes from slitless in this instrument, which means high throughput. The throughput advantage of this instrument over StFT imaging spectrometer based on Sagnac interferometer is presented. The principle and the system configuration are described. Several preliminary experimental results are shown.
