<P>PROBLEM TO BE SOLVED: To provide a scanning type display device optical system that can project an optional full color image, match a super-high resolution image of full specification nearest to natural colors, and cope with a three-dimensional full color image that looks deep in depth, which are hard to be achieved in a conventional projection device, by performing separation and synthesis with light having wavelength not limited by three primary colors of white light, performing desired color separating adjustment control by a DMD, to achieve a delicate hue. <P>SOLUTION: The scanning type display device optical system separates light from a lamp 1 for each wavelength by a concave diffraction grating 7, performs the adjustment for each separated wavelength by the DMD 8, and performs synthesis for each wavelength by a concave mirror 9, to project a full color image of an optional color. <P>COPYRIGHT: (C)2011,JPO&INPIT |
