HyPlant

HyPlant is a novel high performance aircraft supported spectrometer to measure sun-induced refection and chlorophyll fluorescence


HyPlant is a high-performance airborne imaging spectrometer for vegetation monitoring developed by the Forschungszentrum Jülich in cooperation with SPECIM Spectral Imaging Ltd (Finland). The senor operates in a push-broom mode and consists of two hyperspectral modules. (A) The dual- imager consists in two sensors integrated in a single housing and with the same fore optics providing contiguous spectral information from 370 to 2500 nm with 3-10nm spectral resolution in the VIS/NIR spectral range and 10 nm spectral resolution in the SWIR spectral range. (B) The fluorescence imager is a special module that acquires data at high spectral resolution (0.25 nm) in the spectral region of the two oxygen absorption bands (670 to 780 nm) and is dedicated to measure the vegetation fluorescence signal.

HyPlant all

Since 2012 we have been producing maps of top-of canopy reflectance and sun-induced chlorophyll fluorescence  from agricultural areas in Germany and Forest areas in Czech Republic and North Carolina, US. Maps of sun-induced chlorophyll fluorescence and additional vegetation parameters are used to monitor actual photosynthesis and stress level responses of vegetation canopies. The obtained results are of great value for supporting studies related to the FLEX explorer mission.
