...for the most demanding field and airborne installations. The most valuable feature of AisaFENIX is its ability to capture the highest quality hyperspectral data over VNIR, NIR, and SWIR wavelengths in a single continuous image. For the first time ever, the user is able to measure for every pixel a perfect spectrum from 380 to 2500nm with up to 620 spectral bands, whatever the targets and the distances to the targets are.

The most prominent environmental, defence and law enforcement applications require high quality hyperspectral data at different wavelength ranges. Often, the more quality spectral information available, the more reliable the results are. This need has resulted in complicated and expensive systems, where two separate imagers have been mechanically co-aligned into a solid platform. The challenge with separate optical systems has been the nearly impossible task of achieving perfect pixel co-registration of the two images (VNIR and SWIR) when the distance to the target is changing.

AisaFENIX images the target in 380-2500nm spectral region through single front optics and a single input slit, keeping all wavebands spatially co-registered independently of the distance to the target. AisaFENIX employs a patent pending “single optics dual channel” imaging spectrograph which, in spite of the single input slit, has two diffraction gratings, one optimized for VNIR and second for SWIR region. Additionally, two focal plane arrays (FPA), a state of the art CMOS and cryogenically cooled mercury cadmium telluride (MCT), are employed in order to maximize sensitivity and signal-to-noise ratio (SNR) in the VNIR and SWIR spectral regions. With two FPAs, different exposure times can be applied in the VNIR and SWIR regions in order to optimally adapt to various spectral illumination conditions. As the imaging spectrograph is extremely compact, AisaFENIX weighs less than 15kg. This represents more than a 75 percent reduction in weight and size when compared to a typical two camera setup.

The affordable cost level, together with unique performance simplicity, reliability and performance in field usage transform AisaFENIX into a versatile tool for a wide range of applications, including...
