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.

A method for displaying an image including: forming at least three light beams by diffraction at a single linear light modulator, wherein the at least three light beams have substantially equal intensity and are substantially the same color; projecting the at least three light beams toward a display surface to form an image line; and, scanning the image line across the display surface to form an image thereby.

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.

A scanning beam display system includes an optical module, an image control module, and a display screen on which optical beams are scanned. The optical module includes a vertical adjuster placed in the optical paths of the beams to control and adjust positions of the optical beams along a generally vertical direction on the display screen, and a control unit configured to receive control instructions for the vertical adjuster and to control the vertical adjuster to be at one of a predetermined number of orientations to place the scanning optical beams at a corresponding distinct position on the display screen. The control unit is further configured to apply an adjustment offset to each orientation of the vertical adjuster such that each immediately vertically adjacent pair of beam footprints projected on the display screen resulting from the plurality of positions have a vertical overlap that is larger than a first threshold.
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.
