Standard Radiation Detectors for Measurements of Diffuse and Parallel Radiant Fluxes 2000-01-2529
Two types of standard radiation detectors, destined for measurements and control of parallel radiant flux and ones with little angle divergence beam (first type) and diffuse radiant flux (second type) are presented in the paper. The sensors of the above detectors correspond to different black bodies. The mathematical models and numerical methods, permitting to evaluate the characteristics of the detectors with taking into account the environmental conditions are developed. The calculation results allow to create the detectors with optimal constructive parameters according to operating conditions of ones. By present time some radiation detectors are manufactured and successfully used for measuring solar and diffuse radiation in a frame of the thermal vacuum tests of aerospace vehicles fragments and materials
