Electro-optical system and method of displaying images
First Claim
1. An electro-optical system comprising a plurality of dye lasers, each of said dye lasers emitting a beam having a wavelength different for each of said plurality of dye lasers, optical aligning means for aligning laser beams as emitted from said lasers with a same axis, optical expanding means for expanding the laser beams aligned with said axis by said optical aligning means, and a light bulb arranged on an extension of said axis accompanied with a display means for separately directing optical images of a plurality of colors to a first surface of said light bulb in synchronism with the operation of said plurality of dye lasers.

Abstract
An electro-optical system such as an image display system and a method of displaying images are described. Laser beams of three primary colors are emitted from three lasers in a time sharing mode. These laser beams are directed onto the same optical path and then separately given optical information from the same optical modulating device in accordance with images of the respective primary colors. By this structure, displacement of constituent color images can be effectively avoided.
