AISAIBIS
The new SPECIM AisaIBIS is a Unique Hyperspectral Imager for Measuring Sun-induced Fluorescence known as “the secret light of plants”. SPECIM’s 20 years of experience of building high quality hyperspectral imagers for airborne and field use, where solid stability and ease of use are crucial once again creates a masterpiece. AisaIBIS with its sampling of 0.11 nm and high light throughput of F/1.7 for the first time meets the challenge of measuring fluorescence from an airborne platform.
THE SECRET LIGHT OF PLANTS During the photosynthesis, plants convert light energy from the sun into chemical energy that is used to fuel organism growth. During that process plants basically absorb one colour and emit another – the fluorescence. Measured fluorescence can be used as an indicator of photosynthetic activity of the plant thus telling its vitality.
TECHNICAL CHARACTERISTICS 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 absorption lines in the specific spectral region of 670 – 780 nm. AisaIBIS meets the challenging requirements that this method places for the instrument. 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.
