摘要: A plant species discrimination experiment was carried out using emissive thermal infrared imaging spectroscopy. This a first application of the Telops HyperCam-LW for vegetation analysis. The is Fourier-transform spectrometer designed airborne, field and laboratory application. Compared to spectrometers, this allows fast measurements at high spectral resolution in 8–12 μm range. paper shows that — measurement setup capable capturing quality information, comparable instruments. We used capture leaf spectra, generally considered as spectrally flat surfaces. Using HyperCam-LW, it possible subtle signatures perform analysis with very good results. Further, potential hyperspectral airborne or spaceborne study focusing on discussed.
