Summary:We presented basic results of the preliminary testing of acousto-optical hyperspectrometer for unmanned aerial vehicle. The image quality is rather high, so the reliable spectra for each spatial element can be reconstructed. The stability of sensing characteristics is studied. It is shown that warming-up of the photodetector as well as of the acousto-optic crystal results in variations of the output signal due to temperature drift. This study places additional requirements upon the system behaviour in changing environment. We discussed results of green leaves testing.
