摘要

To obtain general knowledge on the spatial nonuni- formity errors of an integrating sphere photometer asso- ciated with the spatial intensity distributions of test lamps, a series of computer simulations have been con- ducted for various designs of an integrating sphere suring different types of lamps. An integrating sphere simulation program, previously developed for the real- ization of the luminous flux unit at NIST, has been uti- lized for this analysis. The program simulates interreflec- tions in an integrating sphere and calculates the final luminance distributions on the sphere wall, as well as the detector output.
