“…For example, an LWIR detector realized by molecular beam epitaxy will be more homogeneous (less than 0.2% of low cut-off wavenumbers inhomogeneities, which corresponds to less than 3.7 cm −1 at σ 1570 cm −1 according to [14]) than a very-long-wave infrared (VLWIR) detector realized by liquid-phase epitaxy (0.45% of low cut-off wavenumbers inhomogeneities, which corresponds to 4 cm −1 at σ 900 cm −1 , according to [15]) and than a VLWIR detector with small wavenumbers (1.7% of low cut-off wavenumbers inhomogeneities, which corresponds to 13.5 cm −1 at σ 790 cm −1 , according to [13]). The measurements made in our laboratory over an IRFPA showed disparities around σ 1900 cm −1 that reached 15 cm −1 (see Subsection 3.A.1).…”

“…For example, Fig. 2 extracted from [13], presents spectral responses of an MCT detector operating in the long-wave infrared (LWIR) spectral range. It illustrates the fact that all the pixels of a given detector do not have the same low cut-off wavenumber (high cut-off wavelength).…”

Relevance of an inverse problem approach to overcome cut-off wavenumbers disparities in infrared stationary Fourier transform spectrometers

One of the major limitations to the use of infrared focal plane arrays (IRFPAs) in stationary Fourier transform spectrometers (FTSs) comes from the spatial inhomogeneities of the pixel responses, where the inhomogeneities of the cut-off wavenumbers of the pixels can prevail. The hypothesis commonly assumed for FTSs that all the pixels are equivalent is thus inaccurate and results in a degradation of the estimated spectrum, even far from the cut-off wavenumbers. However, if the individual spectral responses of the pixels are measured beforehand, this a priori information can be used in the inversion process to produce reliable spectra. Thus, spatial inhomogeneities are not an obstacle for the use of infrared stationary FTS. This result is illustrated in this paper by numerical simulations, based on a realistic description of an IRFPA.

“…To access the total radiometric performances of SWI channels, performance tests and evaluation for the combination of SWI detector, pre-amp (trans impedance amplifier), and analog signal processor has been conducted.

The stiring cycle cooler has many space application heritages such as ASTOR-F and SELENE.…”

The Global Change Observation Mission (GCOM) is the next generation earth observation project of Japan Aerospace Exploration Agency (JAXA). GCOM concept will take over the Advanced Earth Observing Satellite-II (ADEOS-II) and develop into long-term monitoring of global climate change. The observing system consists of two series of medium size satellites: GCOM-W (Water) and GCOM-C (Climate). The Second-generation Global Imager (SGLI) on GCOM-C is a multi-band imaging radiometer in the wavelength range of near-UV to thermal infrared. SGLI will provide high accuracy measurements of Land, Ocean, Atmosphere, and Cryosphere. This paper describes design and breadboarding activities of the SGLI instrument.
