Reflective surfaces symmetrical imaging device, a manufacturing method of the spatial image display device and the reflective surface symmetric imaging element

摘要

The present invention relates reflective surfaces symmetrical imaging device can be made inconspicuous an optical errors plurality of elements have to provide a producing method of the spatial image display device and the reflective surface symmetric imaging element. Comprising A first layer 22 which rectangular unit mirror sheet 24 is arranged a second layer 23, the unit mirror sheet 24 constituting the second layer 23, plural constituting the first layer 22 by being laminated so as to straddle the unit mirrors sheet 24, the boundary between the unit mirror sheet 24 of the first layer 22, a boundary between unit mirror sheets of the second layer 23 are offset from each other. .FIELD 3
