摘要： A headup display apparatus consists of a projection optical system unit installed in the dashboard of a car and a reflection member on the windshield. The projection optical system unit contains an indicator and an off-axis reflective hologram which reflects display light of the indicator toward the windshield, which in turn reflects it toward the viewing point of a driver. As a result, the display is seen superimposed on the exterior view. When external light as from the sun enters the projection optical system unit traveling in a direction reverse to the path of the display light, the off-axis reflective hologram reflects the incident external light toward a direction different from that of the outgoing display light to minimize an abnormal illumination of the indicator surface which would otherwise render the display unrecognizable. Behind the hologram is installed a heat dissipating member that receives infrared rays that have transmitted the hologram in order to dissipate heat.

摘要： A hologram of a virtual object or an object which actually exists is formed and a solid image is displayed. 3-dimensional information of the object to be displayed is divided into regions in the depth direction. Depth images are formed as 2-dimensional images where are seen from a plurality of points which are obtained by finely dividing the hologram forming surface for every region. A phase distribution at the hologram forming surface is calculated from the depth images and displayed on a liquid crystal display or the like as an electronic hologram. A reference light is irradiated onto the display and is converted into an optical wave front, thereby displaying a solid image. When forming a hologram recording medium, a zone image corresponding to each of the finely divided exposure regions of a dry plate is exposed multiple times.

摘要： A hologram surface to express a phase distribution, a visual field in which a solid image can be seen; and a stereoscopic display limit are set in a virtual space. A target to be stereoscopically displayed is subsequently expressed in the virtual space by a set of micro polygons. A plurality of slice planes which are parallel with the horizontal plane are set into the virtual space including the target. The line segments which intersect the polygons are obtained for every slice plane. The detected line segment is divided or clipped as necessary and is finally divided into the portion which can be always seen from the whole region of the visual field and a portion which is obstructed by another line segment and can be seen from only a part of the visual field, thereby extracting the line segment. In the calculation of a phase distribution, sampling points are set onto the extracted line segment, a 1-dimensional hologram phase distribution on the hologram surface is calculated for every sampling point, and the calculated 1-dimensional hologram phase distributions are added to every slice plane.

摘要： A diffraction light modulated by a plane type phase distribution display device is deflected by an image formation optical system and is formed as an image onto a cylindrical screen surface and is diffused in the vertical direction by a unidirectional light diffusing section such as a lenticular lens or the like, so that a stereoscopic image can be seen. As a phase distribution display device, a liquid crystal device having pixels on the order of the wavelength in the circumferential direction and having coarse pixels in the radial direction is used. Thus, it is equivalent to that the phase distribution display device is located on the cylindrical surface. A cylindrical stereoscopic display can be performed by using the plane phase distribution display device.

摘要： An image display to display a 2-dimensional image and a beam deflector to deflect the lights from the pixels constructing the image of the image display are provided. The beam deflector is arranged closely in front of the image display. A plurality of 2-dimensional images of different visual directions are sequentially displayed in the image display. The light from each pixel is deflected by the beam deflector synchronously with the display of the 2-dimensional image so that the light from each pixel is directed to the region in which the visual point has been set in order to obtain each image. The switching operation in this instance is executed at a high speed.

摘要： A plurality of 2-dimensional images of different visual directions, when an object to be displayed is seen from different directions, are inputted to an input section by photographing an object using cameras. The 2-dimensional images are then subjected to enlargement, reduction, and movement of the coordinate position, thereby adjusting the size and position of the solid image. A phase distribution at a hologram forming surface is then calculated by a phase calculating section. The phase distribution is calculated from a plurality of 2-dimensional images of red, green, and blue components, and the reproduction light of each color is irradiated, thereby displaying a color solid image. The calculated phase distribution is expressed on a hologram forming surface of a phase expressing section using a display. A reproduction light is then irradiated and converted into an optical wave front, to thereby display a solid image. The 2-dimensional images obtained by photographing can be also formed by interpolating calculations from the two 2-dimensional images which were acctually photographed.
