Abstract
An image display device using a one-dimensional hologram is disclosed. The image display device includes a light deflection unit which deflects a parallel light ray and adjusts the incident angle of a reconstructing light in sequence, and a one-dimensional hologram optical modulator which reproduces the entire picture by updating each lineal picture in sequence. A one-dimensional hologram is capable of expressing one lineal picture at one time with single axes data. The one-dimensional hologram is updated in synchronization with the incident reproducing light. The input data for a one-dimensional hologram may be computed by an optical calculation method.
Claims5
In a video display device, an improved image display device using a one-dimensional hologram, comprising:
- a light deflection means which sequentially deflects a parallel ray and adjusts a reproducing light incident angle to a one-dimensional hologram;
- and
- a one-dimensional hologram light modulation means which expresses one line picture at one time with single axes data, and reproduces an entire picture by sequentially updating each lineal picture in synchronization with the adjusted incident reproducing light.
