Filed: 1988-12-12
Abstract: PURPOSE:To shade off a boundary part and to attain soft observation by gradually reducing the diffraction efficiency of the peripheral part of a hologram sheet provided on a transparent sheet in the direction of an edge part. CONSTITUTION:A hologram at a diffraction efficiency eta1, which reproduces display information as a three-dimensional image, is recorded on window glass 1 of an automobile.
