The spectral calibration method discussed in this paper is mainly aimed at a solar spectral irradiance radiometer based on correlation photon absolute radiometric calibration [6], [11], [23]. This absolute radiative calibration method is based on the strict spatiotemporal correlation of photons in the SPDC effect [13].
Electrical substitution radiometers.Based on the principle of electrical substitution (and/or electrical compensation), first applied by Angström in 1893 (Ångström 1894; Angström 1899), these instruments are self-calibrated and considered as primary absolute radiometers.The principle of substitution assumes that heating produced by the …
Some existing solar tower power plants do not use a method of measuring heliostat orientation online, but merely a recurrent calibration method. During solar operation, a single heliostat is moved from the receiver to a calibration target (this is, for example, a white area below the receiver), whereby the offset of the resulted light spot …
