Abstract
Disclosed herein are an apparatus and method for forming a 3D holographic image using non-periodically structured optical elements. The 3D holographic image apparatus includes a light source configured to radiate light, a spatial light modulator configured to modulate the light projected by the light source, and a non-periodic optical element configured to modulate incident light by refracting, diffracting or reflecting the direction of the incident light in a plurality of directions when the light modulated by the spatial light modulator is incident. A 3D holographic image may be formed based on the light modulated by the non-periodic optical element.

A three-dimensional (3D) holographic image apparatus, comprising:
- a light source configured to radiate light;
- a spatial light modulator configured to modulate the light projected by the light source;
- and
- a non-periodic optical element configured to modulate incident light by refracting, diffracting or reflecting a direction of the incident light in a plurality of directions when the light modulated by the spatial light modulator is incident, wherein the optical elements of the non-periodic optical element are physically non-periodically arranged but not randomly arranged, and wherein the non-periodic optical element includes at least one of a pinhole array in which pinholes have been physically arranged in a predefined non-periodical way, and a holographic optical element, and
- wherein a 3D holographic image is formed based on the light modulated by the non-periodic optical element.
A three-dimensional (3D) holographic image method, comprising steps of:
- modulating light projected from a light source by a spatial light modulator;
- and
- making incident the modulated light on a non-periodic optical element and modulating the incident light by refracting, diffracting or reflecting a direction of the incident light in a plurality of directions, wherein the optical elements of the non-periodic optical element are physically non-periodically arranged but not randomly arranged, and wherein the non-periodic optical element comprises at least one of a pinhole array in which pinholes have been arranged in a predefined non-periodical way, and a holographic optical element, and
- wherein a 3D holographic image is formed based on the light modulated by the non-periodic optical element.
