Abstract

PURPOSE:To change the spectral energy distribution of the incident light to the original surface, by illuminating the transmission original with plural light sources different in spectral energy characteristic simultaneously. CONSTITUTION:Distances between transmission original (a) and fluorescent lamps (b) and (c) different in spectral energy distribution are changed independently by distance changing means (e), thereby obtaining a desired spectral energy distribution of the reflection light from the original.
