Static polarization interference imaging spectrometer (SPIIS)

Abstract

A static polarization interference imaging spectrometer (SPIIS) was developed based on a single birefringent component. When it is launched on the satellite (or aeroplane), it will produce an interferogram and target s image in the spatial domain which is recorded using a 2D CCD camera with device s pushbroom.The spectrum of the target is reconstructed from the Fourier transform of the interferogram. The polarization interference imaging device has advantages of ultra-compact, static, wide field of view, high throughout. In laboratory, a series of images and interferogram are obtained using our principle device under module own pushbroom.
