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： 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.

摘要： A space light modulating apparatus and a stereoscopic display apparatus which are used in a rewritable hologram stereoscopic display. A solid image can be properly displayed by a phase distribution of a low spatial frequency. A plurality of flat space light modulating units, each having a predetermined area for performing a wave front conversion while setting a position near the position of a cross point (center position) of a normal line from a virtual display surface of a non-flat shape to display the phase distribution into a producing position of a solid image, are arranged along the virtual display surface such as a cylindrical surface or a spherical surface.

摘要： In a method and apparatus for displaying a stereoscopic image, a plurality of 2-dimensional images having parallaxes in only horizontal directions are obtained and inputted when an object to be displayed is seen from different positions in the horizontal direction. The 2-dimensional image is divided in the vertical direction into 1-dimensional line images which are elongated in the horizontal direction. A phase distribution of a corresponding hologram segment is calculated from the pixels of the line image. The calculated phase distribution is displayed on a hologram forming surface of a phase displaying section using a display. A reproduction light is irradiated and converted into an optical wave front and is further enlarged in the vertical direction, thereby displaying a solid image. The 2-dimensional images are inputted by photographing the object by a plurality of cameras arranged in the horizontal direction. The 2-dimensional images can be also produced by interpolating calculations from two 2-dimensional images which were actually photographed. The 2-dimensional images which are used in the phase calculations are subjected to a process such as enlargement, reduction, or movement of the coordinate position, thereby adjusting the size and position of a solid image.

摘要： An apparatus for deflecting light of the present invention comprises: (a) at least one pair of transference electrodes arranged facing one another; (b) a drive circuit which applies a voltage among the transference electrodes; and (c) a liquid crystal which is inserted among the transference electrodes, and whose parallel stripes that function as a diffraction grating when the voltage is applied among the transference electrodes are produced at a pitch corresponding to the applied voltage. The light can be scanned if a diffracted light by the apparatus for deflecting light is converted into a scanning light and a voltage value is changed temporally to apply the voltage among the transference electrodes. In a device for reading information, the scanning light is reflected in a bar code and the reflected light is detected by an apparatus for detecting light. In a device for stereoscopic display of the present invention, the apparatus for deflecting light is used as beam deflection means for deflecting the light beamed from a picture element which organizes the pictures of the picture display means.
