Abstract: 영상 투사 장치가 개시된다. 광원은 서로 다른 파장을 갖는 복수의 단색광을 방출한다. 제1광전달부는 각각의 단색광이 통과하는 복수의 광섬유로 이루어진다. 광스위치부는 MEMS(Micro Electro Mechanical System) 기술에 의해 제조된 복수의 고반사 미러로 이루어지며 단색광을 소정의 각도로 선택적으로 반사시킨다. 면광원화부는 반사된 단색광을 균일하게 면광원화한다. 패널은 면광원화된 단색광을 입력받아 상단, 중단 및 하단 중 적어도 어느 하나의 단에 단색색띠를 형성한다. 따라서, 광스위치를 이용함으로써 3판식 패널과 같은 광이용 효율로 단패널에 단색색띠를 형성할 수 있으며 고화질의 영상을 구현할 수 있다.

Abstract: An image projection apparatus and method includes a light separating unit that separates white light into monochromatic lights of different wavelengths, and then forms a plurality of monochromatic color stripes. A galvanometer receives the separated monochromatic lights and deflects the lights by a predetermined angle. The holographic optical element such as a hologram element can be used as the light separating unit, obtaining an advantageous reduction in light loss. Further, when the separated RGB monochromatic lights are scanned on the DMD panel by the use of galvanometer, only one color stripe is projected to be incident on the DMD panel in the initial scanning, thereby increasing light utilization efficiency. As a result, the quantity of light increases, the light efficiency improves, and the brightness of the realized image is enhanced.
