Abstract
The optical mixer disclosed enables, through optic fibers, a precise superimposition, in a plane of observation, of identical elementary images with distinct chrominance values. It comprises n (n being a whole number greater than 1) display devices to form n monochrome elementary images with different chrominance values on n screens using one and the same original image, and an optical mixing device formed by optic fibers which may be arranged in sheets. These sheets are ordered to form groups of n fibers wherein the fibers of one and the same group terminate, at their first end, respectively at the n screens, in dots of the elementary images corresponding to the same dot of the original image and terminate, at their second end, in the plane of observation, substantially in a dot corresponding to the dot considered, for the group of the original image.
