Title:
STEREOSCOPIC IMAGE FORMING DEVICE AND METHOD FOR MANUFACTURING STEREOSCOPIC IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/003730
Kind Code:
A1
Abstract:
The present invention provides a stereoscopic image forming device that is formed into an annular shape or a shape using a partially annular shape in planar view, and a method for manufacturing the same. The stereoscopic image forming device is configured such that: a plurality of cross-sectionally triangular grooves 19 having a vertical surface 17 and a slope 18 and a plurality of cross-sectionally triangular projections 20 formed between adjacent grooves 19 are each arranged radially with a reference point X as a center on one side of a transparent flat material 16, and a plurality of cross-sectionally triangular grooves 29 having a vertical surface 27 and a slope 28 and a plurality of cross-sectionally triangular projections 30 formed between adjacent grooves 29 are each arranged concentrically with a reference point Y as a center on one side of a transparent flat material 26; reflective metallic surfaces 37, 38 are formed on the vertical surfaces 17, 27 of each of the grooves 19, 29; the grooves 19, 29 are filled with a transparent resin having a refractive index identical to or approximately identical to the refractive index of the transparent flat materials 16, 26; and the transparent flat materials 16, 26 are stacked and bonded with the grooves 19, 29 facing each other.
