Abstract
An optical apparatus using a single source of white light has five independent channels each of which divides that light into three spectral components, and supplies those components individually through individual attenuators for use as a set of fifteen separate and independently-controllable light sources. Fiber optics light conductors bring light from those sources to a transform filter in a Fourier transform optical system.
