Abstract
An image projecting apparatus including a light source emits a plurality of monochromatic rays of light with different wavelengths. A condenser lens concentrates the plurality of monochromatic rays. A first color separating unit rotates and selectively causes the plurality of monochromatic rays to be reflected therefrom or passed therethrough. A second color separating unit selectively causes the plurality of monochromatic rays that are passed through the first color separating unit to be reflected therefrom or passed therethrough. A square beam generating unit is inputted with the plurality of monochromatic rays reflected from the first and the second color separating units and transforms the monochromatic rays as inputted into square beams. A panel unit is inputted with the square beams of the monochromatic rays and forms a plurality of monochromatic images corresponding to the monochromatic rays.
