A photosensitive recording medium comprises a composition containing a radical-polymerizable monomer, a cationic-polymerizable monomer, a radical polymerization initiator, and a cationic-polymerization initiator as main constituents. A method of producing a hologram comprises a first step of preparing the photosensitive recording medium; a second step of exposing the medium to an interference pattern of radiation rays; and a third step of exposing the entire region of the medium to light; and optionally a fourth step of heating the entire of the medium.

Photosensitive recording medium and method of preparing volume type

An image display apparatus in which luminance contrast is produced by the act of scanning of electron beams is disclosed. The apparatus of this invention includes: a screen including a plurality of picture elements each having a plurality of miniature luminescent units which respectively exhibit luminescence in response to the application of a plurality of electron beams, the picture elements being arranged in lines and columns; electron-beam generating means for generating the plurality of electron beams which respectively define the plurality of miniature luminescent units in each of the picture elements; control means for controlling emission of the plurality of electron beams so that the number of the miniature luminescent units which exhibit luminance in each of the picture elements may be controlled in accordance with a video signal; and/or means for controlling emission the period of time available for the emission of at least one of the plurality of electron beams.

Image display apparatus

A display apparatus having an image generator and a beam combiner including a hologram for displaying a reduced image by receiving beams from the image generator. A virtual image of an image generated by the image generator is formed in the vicinity of the beam combiner by virtue of the image reductioning function of the beam combiner, so that the displayed image is visible from a wider range of viewing positions.

Display apparatus for a head-up display system

A head-up display device comprises an image generator, a beam combiner having a light receiving plane tilted laterally for receiving a light from the image generator and diffracting the light, and a compensator arranged between the image generator and the beam combiner for receiving the light from the image generator by a light receiving plane thereof and directing the light to the beam combiner to correct an aberration created by the beam combiner. The compensator is arranged such that a normal line extending through a center of the light receiving plane thereof and a normal line extending through a center of the light receiving plane of the beam combiner are in a common plane.

Head-up display device

An image forming device having an electron beam generating device is provided which comprises a plural number of electron beam generating sections and a deflecting means capable of deflecting the group of electron beams emitted from this electron beam generating device in the two directions of X and Y.

Image forming device with beam current control

A display device has an electron ray generating unit of matrix electrode structure in which a plurality of cold cathodes generating electron rays are arranged two-dimensionally, image storing apparatus for storing therein image information as an amount of charges by a variation in a surface potential produced by the application of the electron rays from the electron ray generating unit, and a display for receiving the application of the electron rays applied from the electron ray generating unit and modulated by the electric charge stored in the image storing apparatus and visualizing the image information.

Display device having first and second cold cathodes

An optical modulation device includes: a ferroelectric liquid crystal disposed between a pair of substrates; provision for applying an alternating voltage sufficient to render the ferroelectric liquid crystal turbid; and provision for superposing a DC voltage on the alternating voltage. A portion of the ferroelectric liquid crystal rendered turbid through the application of an alternating voltage is selectively caused to have an increased transmittance when superposed with a DC voltage.
