Specim Aisa Series Hyperspectral Imaging Cameras

Specim’s AisaFENIX 1K, the full spectrum hyperspectral camera is an ideal solution for remote sensing of the environment and other aerial survey applications. The AisaFENIX 1K hyperspectral sensor with 1024 spatial pixels takes the productivity of hyperspectral imaging to an entirely new level. It produces the same top quality full spectrum hyperspectral data as does its forerunner, AisaFENIX and, at the same time, reduces the flight costs by 60%, because less flight lines are required.

Features:

• VNIR and SWIR wavelengths from 400 nm to 2500 nm
• Readily co-registered data with common front optics
• Excellent signal-to-noise ratio and stability
• Compact for installation on standard gyro stabilised standard airborne camera mounts, as well as turrets and medium-sized UAVs
• Supports 4 different GNSS/IMU systems

Specim’s AisaKESTREL, the first professional quality hyperspectral sensor range, intended for UAVs and other platforms of limited payload size. AisaKESTREL 10 (400 – 1 000 nm) and AisaKESTREL 16 (600 – 1 640 nm) are built to the same strictest data quality requirements as Specim’s world renowned AisaEAGLE and AisaFENIX sensors, using the experience gathered through 20 years of airborne hyperspectral remote sensing.

AisaIBIS a robust and very high spectral resolution hyperspectral imager for ground and airborne measurement of sun induced fluorescence from plants.

Specim created AisaIBIS together with Juelich Research Centre from Germany, as the Hyplant sensor, for the European Space Agency’s (ESA) Earth Explorer programme called FLEX. The project aims at providing global maps of vegetation fluorescence, which can be converted into an indicator of photosynthetic activity. AisaIBIS works as a precursor for a potential satellite instrument, and is used to produce airborne data for the development of fluorescence measurement.

AisaIBIS is designed to measure the sun induced fluorescence with the so-called Fraunhofer Line Depth Method. In this method the weak fluorescence signal is detected and quantified at the bottom of the two oxygen absorbtion lines in the specific spectral region of 670 – 780 nm. By applying Specim’s high light throughput (F/1.7) imaging spectrometer, and novel sCMOS camera technology, low noise, high dynamic range and signal-to-noise ratio are achieved with excellent spectral sampling (0.11 nm) and superb image quality even at the high image rate required in flight conditions.
