Abstract

In this paper, the Bidirectional Reflectance Distribution Function (BRDF) and the directional radiance factor are applied to the construction of a universal equation for IR parameter measurement. The ambient radiation is also divided into two parts--the uniformand the nonuniform. The universal equation is also applied to the quantitative error analysis, which will be helpful to perfect and improve the IR devices and measurement methods. It is shown that the theoretical results correspond to the experiment results. Furthermore, the universal equation is also applied to the emissivity measurement to present an active method in which the results are in good agreement with those obtained with the box method.
