“…12 The HIMP is an interactive, spreadsheet-based computer model, which has modeled performance for several Fourier transform hyperspectral imagers, including the Kestrel VFTHSI 13 and MightySat II.1. 14,15 The HIMP includes parameters that allow the specification of numerous target, atmospheric, instrumental, geometrical, and detector characteristics, as well as a variety of graphical outputs. The HIMP also models fringe visibility, the top hat function (fill factor was set to 50%), modulation transfer function, read noise, dark noise, and photon noise.…”

Hyperspectral remote sensing is experiencing a dazzling proliferation of new sensors, platforms, systems, and applications with the introduction of novel, low-cost, low-weight sensors. Curiously, relatively little development is now occurring in the use of Fourier transform (FT) systems, which have the potential to operate at extremely high throughput without use of a slit or reductions in both spatial and spectral resolution that thin film based mosaic sensors introduce. This study introduces a new physics-based analytical framework called singular spectrum analysis (SSA) to process raw hyperspectral imagery collected with FT imagers that addresses some of the data processing issues associated with the use of the inverse FT. Synthetic interferogram data are analyzed using SSA, which adaptively decomposes the original synthetic interferogram into several independent components associated with the signal, photon and system noise, and the field illumination pattern.

We discuss early hyperspectral research and development activities during the 1990s that led to the deployment of aircraft and satellite payloads whose heritage was based on the use of visible, spatially modulated, imaging Fourier transform spectrometers, beginning with early experiments at the Florida Institute of Technology, through successful launch and deployment of the Visible Fourier Transform Hyperspectral Imager on MightySat II.1 on 19 July 2000. In addition to a brief chronological overview, we also discuss several of the most interesting optical engineering challenges that were addressed over this timeframe, present some as-yet un-exploited features of field-widened (slit-less) SMIFTS instruments, and present some images from ground-based, aircraft-based and satellite-based instruments that helped provide the impetus for the proliferation and development of entire new families of instruments and countless new applications for hyperspectral imaging.

“…The launch of the first Fourier Transform HyperSpectral Imager (FTHSI) on board of US Department of Defence (DoD) technological satellite MightySat II.1 was an attempt to overcome the main drawbacks that limit the use of push-broom and whisk-broom imaging spectrometers for environment investigation (Meigs et al, 1997;Otten III et al 1997, 1998.…”

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.
