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.
