technical field [0001] The invention relates to a multi-angle fully automatic surface fine emissivity spectrum acquisition system device, which can automatically collect and store the infrared off-the-ground radiance spectrum of samples under different observation angles, and obtain the corresponding infrared spectral regions corresponding to different observation angles through calculation The fine emissivity spectral lines of the samples can play an important role in the fields of surface temperature and emissivity remote sensing inversion and verification. Background technique [0002] The surface emissivity is defined as the ratio of the thermal radiation emitted by the surface to the thermal radiation emitted by a black body at the same temperature. It is related to factors such as surface composition, surface roughness, wavelength, and soil moisture. Surface emissivity is a key characteristic parameter in thermal infrared remote sensing inversion, which plays an equal...
