ON THE UNIFORMITY OF THE ILLUMINATION-DISTRIBUTION ON THE WINDOW OF AN INTEGRATING SPHERE
积分球出光窗上照度分布均匀性的研究

In this paper we analyzed the uniformity of the illumination-distribution on the window of an integrating sphere and obtained the distribution function determined by the geometrical parameters of the sphere. On the basis of this result, we discussed the condition of existence of the equi-illumination circle and also such problems as the calculation of the blind region.
