AisaFENIX delivers the highest quality hyperspectral data available in VNIR, NIR, and SWIR wavelengths (380 nm – 2 500 nm) in a single continuous image. The instrument has excellent transmission (>65%), signal-to-noise ratio SNR (600 – 1 000) and sampling interval (620 bands).
As the AisaFENIX hyperspectral sensor offers extreme ruggedness and 75% reduction in size and weight, it can also be fitted in turrets and medium sized UAVs. The excellence in technical performance and physical size has been achieved through innovative and unique “single optics dual spectrograph” design.
Environmental analysis and law enforcement applications require high quality spectral data at different wavelength areas. The more spectral information available, the better and more reliable the analysis results are. This need has previously resulted in complicated and expensive multi-sensor systems.
AisaFENIX hyperspectral sensor eliminates past challenges in “full spectrum imaging”. It is a single optics imager, with two focal plane arrays always staring exactly the same spot of the object. Thus, there is no need for the co-alignment of two separate imagers with different distortions, sharpness, and FOV.
The patent pending AisaFENIX hyperspectral sensor images the target in 380 – 2 500 nm spectral region through single front optics and single input slit, keeping all wavebands spatially perfectly co-registered independently of the distance to the target. AisaFENIX employs SPECIM’s 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.
Also, two focal plane arrays (FPA), a state of the art CMOS and cryogenically cooled Mercury Telluride Cadmium (MCT), are employed in order to maximize sensitivity and signal-to-noise ratio (SNR) in the VNIR and SWIR spectral region.
With two FPAs, different exposure times can be applied in the VNIR and SWIR region in order to optimally adapt to various spectral illumination conditions. The imaging spectrograph is extremely compact, and makes it possible to integrate the full spectrum AisaFENIX imager in less than 15 kg, more than a 75 % reduction in respect to a typical two camera setup.
