Title:
REFLECTIVE PLANE-SYMMETRICAL IMAGE-FORMATION ELEMENT, SPATIAL VIDEO IMAGE DISPLAY DEVICE, AND METHOD FOR MANUFACTURING REFLECTIVE PLANE-SYMMETRICAL IMAGE-FORMATION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2013/175626
Kind Code:
A1
Abstract:
[Problem] To provide a method for manufacturing a reflective plane-symmetrical image-formation element capable of reducing the prominence of optical error present in a plurality of elements, a spatial image display device, and a method for manufacturing the reflective plane-symmetrical image-formation element. [Solution] The present invention has a first layer (22) and a second layer (23) in which rectangular mirror sheet units (24) are arranged, the mirror sheet units (24) constituting the second layer (23) being stacked so as to extend over a plurality of mirror sheet units (24) constituting the first layer (22), whereby the boundaries between the mirror sheet units (24) of the first layer (22) and the boundaries between the mirror sheet units of the second layer (23) are displaced relative to one another.
