Calculation of spatial response distribution function of an integrating sphere for LED total luminous flux measurement using a commercial Monte-Carlo ray-tracing simulator
This work presents spatial response distribution function (SRDF) calculation of an integrating sphere using 2 independent methods; a commercial Monte-Carlo ray-tracing simulator and our own codes based on iterative integration of the radiative trasfer. To test feasibility of the two methods, we simulated the spatial throughput of an Ulbright-type integrating sphere with both methods separately, and compared each of the result with the previous report. As a result, all of them show a good agreement. In addition, we introduce its application to design a sphere configuration for LED total luminous flux measurement in the same way as the absolute integrating sphere method developed by NIST.
