Title:
STEREOSCOPIC IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/119622
Kind Code:
A1
Abstract:
[Problem] To provide a stereoscopic image display device that makes images with disparity viewable over a wide range of a diffusion surface. [Solution] A stereoscopic image display device (1) is provided with: an optical element (50) having n regions provided so as to correspond to each of n (n being an integer of 2 or higher) images with disparity for obtaining diffusing coherent light for each; an irradiating device (60) that irradiates the optical element with coherent light and scans the n regions with the coherent light; an optical modulator (30) that is illuminated by the diffused coherent light incident to each position on the optical element from the irradiation device, synchronizes for scanning the n regions with the coherent light, and generates modulated images corresponding to each of the n regions; and a projection optical system (20) that superimposes and projects each of the n images with disparity that have been generated by the modulated images onto the same surface at different angles.
