Abstract:
The present invention relates to a method and an apparatus to implement holography using a light source simulation and, more specifically, to a method and an apparatus to implement holography based on a computer using a simulation program capable of controlling a light source by a graphic using brightness information and wavelength of an LED light source in a computer environment. To achieve this, the apparatus to implement holography using a light source simulation of the present invention includes: a storage unit to store at least two light sources combining a hologram image, an intensity of the light source, a frequency of the light source, a position of the light source, a color of the light source, and a color and an intensity of a background light source; a display unit to display one type of light source of the hologram image and at least two light sources; and a control unit to irradiate the hologram image in at least one type of a light source combining the intensity of the light source, the frequency of the light source, the position of the light source, the color of the light source, and the color and the intensity of the background light source.

Abstract:
Provided are a holographic printer and a holographic printing method. The holographic printer according to an embodiment of the present invention comprises: an optical modulation unit for displaying a holographic fringe pattern for a certain portion of an object and diffracting an incident wave; and a filtering unit for shielding a component in the diffracted wave field outputted from the optical modulation unit to be transmitted to a certain area of a holographic recording medium. The holographic printer can partially record the holographic fringe pattern in the holographic recording medium in a hogel unit so that the more realistic hologram can be recorded. Furthermore, the holographic printer filters the diffracted wave field outputted from the holographic fringe pattern to record the holographic fringe pattern while removing the unconformable components, thereby eliminating a tiling phenomenon of the hologram.
Abstract:
PURPOSE: A holographic reproducing apparatus and a method thereof are provided to reduce visual fatigue of a user and to supply complete three-dimensional image such as a real object. CONSTITUTION: A light separation unit(310) reflects a light coming out from a light source. A reflective spatial modulation unit(320) performs spatial light modulation reflected from the light separation unit. The reflective spatial modulation unit transfers a generated holographic to both eyes of a user. A mask removes a DC component which is generated from the reflective spatial modulation unit. The mask is arranged in a rear side of a lens which focuses a light through the light separation unit.
Abstract:
PURPOSE: A 3D image playing device and a method thereof are provided to perform Fast Fourier Transform regardless of resolution of a fringe pattern, thereby playing a hologram having the same resolution. CONSTITUTION: A recording medium stores a fringe pattern for playing a hologram. Fast Fourier Transform units(310) divide the fringe pattern into a segment having a fixed size and performs Fast Fourier Transform about the fringe pattern recorded in the divided segment. An adding unit adds the fringe pattern of segments which the Fast Fourier Transform is performed. Phase shifting units(320) shift the changed fringe pattern. [Reference numerals] (310) FFT unit; (320) Phase shifting unit
Abstract:
PURPOSE: A hologram transcoding device and a method thereof are provided to control the number of divided segments according to resolution of a fringe pattern, thereby playing an hologram with the same resolution. CONSTITUTION: A recording medium stores a fringe pattern for playing a hologram. A Fast Fourier Transform unit(30) divides the fringe pattern into a segment having a fixed size and performs Fast Fourier Transform about the fringe pattern recorded in the divided segment. An adding unit adds the fringe pattern of segments which the Fast Fourier Transform is performed. A phase shifting unit shifts the fringe pattern changed by the Fast Fourier Transform unit.
