Abstract
An image projecting apparatus having an optical switch of a non-square matrix structure, is provided. A light source emits a plurality of monochromatic lights having different wavelengths. A first light transmission unit includes of a plurality of optical fibers that allows monochromatic lights to be passed therethrough. An optical switch unit has a plurality of non-square matrix type reflecting mirrors to selectively reflect the monochromatic lights. The reflecting mirrors includes a first group placed at odd lines and a second group placed at even lines. A square-beam generation unit converts reflected monochromatic lights into square beams, and a panel transmits the monochromatic lights converted into square beams and forms monochromatic signals of a predetermined size.
