摘要:
An information recording medium manufacturing method includes steps of forming, on a support, a recording layer containing a polymer compound having an azobenzene structure, irradiating the recording layer with first writing light to form a first light-diffracting structure having a three-dimensional relief pattern on the surface of the recording layer, fixing the relief pattern by forming a deformation preventing layer on the surface of the recording layer, and irradiating the recording layer having the fixed relief pattern with second writing light to forcedly inhibit deformation caused by the movement of molecules, thereby forming a second light-diffracting structure having a refractive index change inside the recording layer.

This invention relates to an improvement in the process for the production of holograms on transparent light-sensitive recording material in which a hologram of an image is recorded or copied by means of actinic light, the image is optionally reconstructed from the hologram by means of non-actinic light, and then at least one further image is recorded or copied onto the same material. The improvement comprises using a recording material having a light-sensitive layer on a transparent support, said light-sensitive layer containing a light-sensitive aromatic diazonium salt, a light-sensitive quinone diazide, or a lightsensitive aromatic substituted nitrone.

Submitted is an image photography play method which is suited to playing a stereoscopic video. The image photography method comprises: a step of forming a hologram pattern from a reference light and a subject light; a step of digitally processing the obtained hologram pattern; a step of writing the digitized hologram pattern as a magnetized vector pattern to a spatial lighting modulator which is formed from a magneto-optical material; and a step of inputting linearly polarized light into the spatial lighting modulator and playing an image according to the digitized hologram pattern.

The present invention provides systems of recording holograms that reduce the writing time, increase the diffraction efficiency, improve the resolution, or restitute color. These systems are well suited for use with an updateable 3D holographic display using integral holography and photorefractive polymer.
摘要:
Information recorded as a hologram in a predetermined position of an optical recording medium is reproduced, and subsequently the reproduced information is re-recorded and retained in the same position as the predetermined position as a hologram. Alternatively, information recorded as a hologram in a predetermined position of an optical recording medium is reproduced, and subsequently the reproduced information is re-recorded and retained in a position different from the predetermined position as a hologram easily.

The present invention relates to polymeric materials that exhibit an erasable photorefractive effect which can be fabricated into optical devices such as optical wave guides.
摘要:
An information processing system is presented for information storage and retrieval with a color center crystal wherein the information to be stored is generated by electrically modulating a light beam, and the information is then stored by forming a hologram of the desired information in the absence of exposure of the crystal to light from the subject.
