Research on Integrating Sphere Light Hole Brightness Attenuation Test System
摘要
Abstract
In order to research the relationship between light brightness attenuation and integrating sphere light hole diameter size, a set of test system is designed by using the SLR camera to get picture of integrating sphere light holes. Then based on research about the ideal integral ball and diffuse reflection theory, the theoretical derivation is carried on and the integrating sphere light holes brightness attenuation factorFR is concluded. In the end, through research of the testing experiment method, a set of feasible test scheme is identified based on Matlab image processing., By analysis of sampled images, it is concluded that the ratio FA of number of pixel points with normal gray value in image spot diameter direction to which in diameter direction. Through comparison between actual integral ball'sFA measured by test experiment and actual integral ball'sFR measured by size calculation, the result shows that the value ofFA locates in the range of the value ofFR, thus validating correctness ofFR. The proposal ofFR can do quantitative analysis for light brightness attenuation of integrating sphere light holes.关键词
