Airborne fluorescence hyperspectral imaging system


The process of light energy being converted to chemical energy for the growth of plants is called photosynthesis. The sun-induced fluorescence is very weak and therefore requires extremely sensitive spectrographs to become visible. AisaIBIS is designed to measure the sun-induced fluorescence. It uses the Fraunhofer line-depth method, where the weak fluorescence signal is detected and quantified at the two oxygen absorption lines in the spectral region of 670 - 780 nm. AisaIBIS is equipped with SPECIM's high light throughput imaging spectrometer that is based on a highly sensitive sCMOS camera with low noise, high dynamic range and high signal-to-noise ratio.

  • Very high spectral resolution
  • Compact and robust
  • High light throughput
  • High frame rate
  • Ground use possible

Further information

AisaIBIS shows excellent spectral sampling of 0.11 nm and a superb image quality in the spectral range of 670-780 nm.  The high throughput imaging spectrograph features an aperture of F/1.7. The system detector is a cooled high-sensitivity sCMOS camera with 768 spectral pixels and 1000 spatial pixels for high spectral and spatial resolution. The signal-to-noise ratio is 680:1, allowing the detection of even the smallest intensities. The camera runs with 100 Hz and the integration time can be freely chosen within the limits of the frame rate. The system comes equipped with a corresponding lens and acquisition software. Its small weight of approximately 14 kg makes it perfectly suited for airborne applications. Other applications can be found in the field or ground environment.
