Abstract
(EN)
A small, inexpensive three-dimensional image display having a structure for displaying a color three-dimensional image sharply even if a low-resolution spatial optical modulating element is used. The three-dimensional image display has an illumination light source unit, a transmission spatial optical modulating element, a lens, and a mask. The illumination light source unit includes three point light sources outputting illumination light components having wavelengths (red, green, blue) different from one another. The point light source outputting the blue illumination light component of the shortest wavelength is disposed in position B (0, 0) on the optical axis of an illumination optical system, the point light source outputting the red illumination light component is disposed in position R (xr, 0), and the point light source outputting the green illumination light component is disposed in position G (xg, 0). An aperture section of the mask is disposed in the region where the zero-order diffracted waves of the reproduction light components of the three wavelengths after subjected to wavefront conversion by the lens are superposed on one another. The illumination optical system determines the direction of incidence of each of the illumination optical components of the three wavelengths on the spatial optical modulation element.

L'invention concerne un petit dispositif d'affichage tridimensionnel bon marché présentant une structure servant à afficher une image tridimensionnelle en couleur nette même lorsqu'un élément de modulation optique spatial à faible résolution est utilisé. Le dispositif d'affichage tridimensionnel comporte un ensemble source de lumière d'éclairage, un élément de modulation optique spatial de transmission, un objectif et un masque. L'ensemble source de lumière d'éclairage comprend trois sources de lumière ponctuelles émettant des composantes de lumière d'éclairage dont les longueurs d'ondes (rouge, verte et bleue) sont différentes. La source de lumière ponctuelle émettant la composante bleue de lumière d'éclairage, présentant la plus petite longueur d'onde, se trouve en position B (0, 0) sur l'axe optique d'un système optique d'éclairage. La source de lumière ponctuelle émettant la composante rouge de lumière d'éclairage se trouve en position R (Xr, 0). La source de lumière ponctuelle émettant la composante verte de lumière d'éclairage se trouve en position G (Xg, 0). Une partie d'ouverture du masque est placée dans la zone où les ondes diffractées d'ordre 0 des composantes de lumière de reproduction des trois longueurs d'ondes sont superposées l'une à l'autre après avoir été soumises à une conversion de surface d'onde par l'objectif. Le système optique d'éclairage détermine le sens d'incidence de chacune des composantes optiques d'éclairage des trois longueurs d'ondes sur l'élément de modulation optique spatial.
