摘要： An apparatus for forming holograms, or reproducing three-dimensional images, without restrictions of three-dimensional images to be reproduced, the size of holograms, or the reference light. When a recording media (1) is irradiated, a controller determines a three-dimensional interference pattern for generating reproduction light corresponding to a desired three-dimensional image, divides the three-dimensional interference pattern into sectional interference patterns, and determines the recording reference light and recording information light for each of the sectional interference patterns. While the recording media (1) is moved, it is irradiated with the recording reference light and recording information light by a head (10) that is also moved by a VCM (13) to change the relative position between the head (10) and the media (1), so that partial holograms are sequentially formed to make a complete hologram.

摘要： When a hologram is irreversibly recorded in a non-photsensitive material by using an interfered femtosecond laser, there occurs a problem that a waveform of pulse laser is distorted by the non-linear optical interaction between the femtosecond laser pulse, the air, and the material, which disables stable recording of embedded hologram. A method for producing a hologram by a two-beam laser interference exposure method uses as a light source a solid laser emitting coherent laser beam with the pulse width (τ) satisfying the relationship: 900 femtosecond

摘要： The invention makes it possible to form a hologram for reproducing a three-dimensional image easily free of limitations placed by the size of the three-dimensional image to be reproduced, the size of the hologram and reference light for reproduction.
A controller calculates a three-dimensional interference pattern for generating reproduction light associated with a desired three-dimensional image when a recording medium (1) is illuminated with reference light for reproduction, divides the three-dimensional interference pattern into partial interference patterns and calculates reference light and information light for recording for each of the partial interference patterns. A final hologram is formed by illuminating the recording medium (1) with reference light and information light for recording using a head (10) while changing the relative positional relationship between the recording medium (1) and the head (10) by moving the head (10) with a VCM (13) while transporting the recording medium (1).

摘要： The invention relates to information technologies and is intended for visualizing three-dimensional images. The technical result of the invention consists in creating electrically controlled three-dimensional phase diffraction gratings and, on their basis, screens for displaying three-dimensional color images. A method for visualizing images comprises directing a beam of broadband optical radiation at a matrix of electrically controlled elements, or pixels, the pixels being supplied with a voltage, its distribution over the matrix being calculated so as to produce a desired change in the current optical characteristics of the pixels, and viewing the image. Moreover, the beam of optical radiation is directed simultaneously at a stack of pixel matrixes in which the matrixes are arranged parallel to one another, the matrixes being irradiated from the side from which the image is viewed, the refraction index being used as a variable optical characteristic of pixels in all the matrixes. The device for performing the claimed method comprises a screen that is a multi-layered structure made of materials transparent to electromagnetic radiation within the optical range, the multi-layered structure comprising alternating layers of material displaying an electro-optical effect and layers of a transparent material that does not display an electro-optical effect, all the layers displaying an electro-optical effect being insulated electrically from one another and each of them being made as a matrix of electrically controlled elements, or pixels.
