Abstract:
An image projection apparatus, comprising:a light source for irradiating a white light; a light separating unit for separating the white light into a plurality of monochromatic lights of different wavelengths, and forming a plurality of monochromatic color stripes from the monochromatic lights, said light separating unit comprising: a square beam generating unit for transforming the white light into a square beam; a linear beam generating unit for transforming the generated square beam into a linear beam; and a color separating unit for separating the generated linear beam into the plurality of monochromatic color stripes; a galvanometer for reflecting the plurality of monochromatic color stripes by a predetermined angle; a digital micromirror device (DMD) panel for receiving the reflected monochromatic color stripes, transforming the received monochromatic color stripes, and reflecting the transformed stripes by a predetermined angle; and a projection lens disposed opposite to the DMD panel.
