Static Imaging Fourier Transform Spectrometer

The general physical model of high etendue static imaging Fourier transform spectrometer is deduced. On the basis of this model the static imaging Fourier transform spectrometer based on the solid Sagnac interferometer is developed. It covers a spectral range of approximately 0.4 mu m similar to 1.0 mu m with 100 resolvable spectral bands. The experimental results are presented.
