Ultra-High Spectral Resolution VNIR

IBIS

A unique hyperspectral imager which measures Sun-induced fluorescence (SIF), an indicator of photosynthetic activity in plants.

The IBIS is a very high spectral resolution hyperspectral imager whose data can be used to derived measures of solar induced fluorescence (SIF), which is an indicator of photosynthetic activity in plants (and e.g. plant health). During the photosynthetic process, plants convert light energy into chemical energy, and in doing so they also emit photons of a very particular wavelength.  The IBIS covers the spectral range 670 – 780 nm in up to 1004 spectral bands at a spectral resolution of 0.275 – 0.305 nm. Data can be provided at pixel sizes between 0.5 and 1 m from a 1 km flying height. Additional applications beyond mapping of SIF can also be conducted with these extremely high spectral resolution data.
