Abstract:
An image projecting apparatus, comprising:a light source configured to irradiate a plurality of monochromatic lights of different wavelengths; a first light transmitting unit comprising a plurality of optical fibers through which the respective monochromatic lights pass; a first optical switch unit comprising a plurality of optical switches in a square matrix arrangement operated to selectively reflect the monochromatic lights; a second optical switch unit comprising a plurality of optical switches arranged in a single file configured to one of reflect and transmit the monochromatic lights reflected from said first optical switch unit, the plurality of optical switches comprising a first group of optical switches arranged in odd-numbered rows and a second group of optical switches arranged in even-numbered rows; a square beam generator configured to transform the monochromatic lights reflected from said second optical switch unit into square beams of a predetermined aspect ratio; a panel unit configured to receive the square beams of the monochromatic lights to realize the received square beams in the form of a monochromatic color stripe of a predetermined size; and wherein either the first or the second group of said second optical switch unit periodically reflects the monochromatic lights.
