Title: Recent advances in Earth remote sensing: Fourier Transform Stationary HyperSpectral Imagers
Issue Date: Feb-2006
Series/Report no.: 49/1
Keywords: Fourier transform imaging spectrometer

hyperspectral remote sensing
Abstract: Future trends for the development of new remote sensing imagers have being defined since the launch of the first Fourier Transform HyperSpectral Imager (FTHSI) on board of DoD technological satellite MightySat II.1. Starting from the analysis of FTHSI optical configuration we have proposed an interesting modification which produces an image of the observed surface superimposed to a stationary interference pattern. This new optical arrangement together with the possibility to accommodate the spectral resolution by changing the device optical aperture and the sensor sampling step make the new instrument interesting for Earth remote sensing purposes. In this paper we present some preliminary results obtained from a laboratory prototype developed at our Institute. Some hints are discussed about the use of such an instrument on board of airborne and satellite platforms.
