Abstract

A well known problem in color TV is the color shading which means a different reproduced color as a function of the position on the screen. This effect results mainly from the angular dependence of the interference layers deposited onto beam splitter prisms. We developed a software which enables us to calculate the relative signal intensities in the three channels Red, Green, and Blue. We use data of the angular dependent spectra of dichroic layers as well as data of the optical system. The influence of different layer systems and trimfilters onto color shading was calculated; the possibility of realizing these layer systems is discussed.
