摘要:
The present invention makes it possible to acquire image information required for displaying a three-dimensional image of an object in a space with a simple configuration and to achieve display of a stereoscopic dynamic image in a true sense with a simple configuration.Light from an object (10) impinges upon a deflecting plate (11). Among the incident beams of light, the deflecting plate (11) allows beams of light at a predetermined angle to the plane of the deflecting plate (11) to pass, the beams exiting as parallel beams of light perpendicular to the plane of the deflecting plate (11). The light passes through a converging lens (12), a pinhole member (13), and a converging lens (14) to impinge upon a CCD (15). An angle of incident light selected by the deflecting plate (11) is sequentially changed as time passes. Therefore, image information output by the CCD (15) becomes plural pieces of two-dimensional image information for which the photographing direction changes as time passes and which serve as image information required for displaying a three-dimensional image of the object in a space.
摘要:
Image information necessary to display a three-dimensional image of an object in a space is acquired with a simple structure, and a three-dimensional dynamic image in a true sense is displayed with a simple structure. Part of light from an object (10) falls on a polarizer (11). The polarizer (11) passes the component of the incident light polarized at a predetermined angle to the surface of the polarizer (11) and allows the component to emerge from the polarizer (11) as parallel light perpendicular to the surface of the polarizer (11). The parallel light passes through a condenser lens (12), a pinhole member (13), and a condenser lens (14) and falls on a CCD (15). The angle of incident light selected by the polarizer (11) can be changed with time. Therefore, the image information outputted from the CCD (15) is a set of items of two-dimensional image information including the direction of imaging changing with time and is necessary to display a three-dimensional image of an object in a space.

摘要:
In a servo operation, position-controlling light, which is red light, is projected onto a recording medium so as to converge to a minimum diameter on a reflecting surface of the recording medium. In a recording operation, information light and recording-specific reference light, each of which is green light, are projected coaxially onto one side of an information recording layer of the recording medium so as to converge to a minimum diameter at an identical position located off the reflecting surface. Information is recorded in the information recording layer in the form of an interference pattern resulting from interference between the information light yet to impinge on the reflecting surface and the recording-specific reference light reflected by the reflecting surface and an interference pattern resulting from interference between the recording-specific reference light yet to impinge on the reflecting surface and the information light reflected by the reflecting surface.

An optical-disk recording method, recording apparatus and reproducing apparatus are provided which are capable of continuously recording/reproducing a hologram with ultra-high density. In the case of recording a hologram to a holographic recording area, a holographic recording spot HSP on one track of the holographic recording area and a holographic recording spot HSP on a track adjacent thereto are recorded in circumferentially different positions. At least one holographic recording spot HSP is formed on each track, making the process continuous. Recording is made such that, provided that the holographic recording spot HSP has a diameter D and a multiplex number of holographic recording spots HSP is m, a pitch P between adjacent holographic recording spots HSP is P=D/m. Consequently, it is possible to efficiently record a hologram with density to a holographic recording area of an optical disk recording medium, and to achieve the density increase of holographic recording capacity.

摘要:
A memory cell array having such a structure that can be realized with a simpler process and ideal for realizing a higher density is provided. Memory cells have a structure in which channel layers (88p and 89p) are formed on the side surfaces of each of a plurality of stacked structures which extends in the Y direction and is periodically formed in the X direction with a gate insulator film layer (9) interposed, and a resistance-change material layer (7) is formed so as to be electrically connected to two adjacent channel layers of the channel layers. Due to such a structure, it is not necessary to perform such a very difficult step that processes the resistance-change material and the silicons collectively and it is possible to provide the memory cell array with a simpler process.
