To quantitatively measure the ambient radiation reflected by a target, in an earlier paper [Zhang et al., Appl. Opt. 25, 3683–3689 (1986)] we presented the equivalent blackbody radiation theory. In this paper we give a theoretical demonstration of that theory and generalize it from the case of an opaque body to the case of a semitransparent body. Several methods are proposed to measure the transmittance, the emissivity, the reflectance, and the true temperature of an opaque or semitransparent body. Good quantitative experimental results are obtained.
