Evaluation of Radiation Flux Efficiency based on Gonio-radiometric Method for Thermal Radiator

Abstract

To measure an angular radiative intensity distribution of thermal radiative heating system is important to estimate reflecting mirror instrument efficiency. For a shape-indpendent measurement, we compared a gonio-radiometric method with radiation-thermometric method. Difference of calculated efficiency was 4% at a thermal radiator within a reflecting mirror. The study suggests that using the gonio-radiometric method would be useful to evaluate a radiative flux of radiative heater with a reflecting mirror.
