    摘要: A display device is disclosed. The display device includes a condenser unit, an illumination lens system, a plurality of diffractive light modulators, a mirror for separating illumination light from diffracted light, a polarized beam separator, a filter unit and a projection unit. The condenser unit converges polarized light, and outputs the converged polarized light. The illumination lens system converts the polarized light into linear parallel light. The diffractive light modulators produce diffracted light beams having a plurality of diffraction orders. The mirror passes the polarized light therethrough using slits, and reflects the diffracted light beams toward a filter system. The polarized beam separator separates the polarized light on a wavelength basis and then allows the separated beams to be incident on corresponding diffractive light modulators, and converges the diffracted light beams and then outputs the converged light to the mirror. The filter system selects the diffracted light beams having desired diffraction orders from among diffracted light beams using a spatial filter. The projection system focuses the diffracted light beams, and projects the focused light beams onto a screen.

    摘要: A projector includes a super-high pressure mercury lamp a spatial light-modulator that modulates a light from the super-high mercury lamp based on an image signal, a projection lens that projects the light modulated, and an optical filter that is used to insert a prism group in the optical path and to remove the prism group that is inserted in the optical path, and a position fixing part that makes a relative-angle between each spatial light-modulator and the prism group constant.

    摘要: A color display apparatus for forming, on a display surface, a color image of superimposed color images, the display apparatus having a first color modulation channel for forming a first color two-dimensional image using a laser light source for providing a first color source beam, a linear spatial light modulator for modulating the first color source beam, and a scanning element for scanning the modulated light beam to form a first color two-dimensional image. A second color modulation channel forms a second color two-dimensional image using an incoherent light source for providing a second color source beam to an area spatial light modulator for modulating the second color source beam to form a second color two-dimensional image. A projection lens then projects a superimposed color image of the first color two-dimensional image and the second color two-dimensional image and any third color two-dimensional image.

    摘要: An object of the present invention is to provide a device that is capable of presenting image information that is larger than an object by irradiating light onto the object that moves on a trajectory that is not known. An object tracking section controls line of sight direction so as to be directed towards a moving object. A rendering section irradiates a light beam in a direction along the line of sight direction. In this way the rendering section can irradiate the light beam onto the surface of the object. It is possible to present information, that has been rendered in a range that is larger than the surface area of the object, to an observer, utilizing an after image of the light beam that has been irradiated on the surface of the object.
