ABSTRACT:
An optical member7is bonded, at its rear side7b, to a holographic stereogram6. The front side7aof the optical member7consists of parallel triangular prisms. Illumination light9is applied to the front surface7aof the optical member7at a predetermined angle of, for example, 60°. The optical member7is made of, for example, optical glass or transparent plastic. Each triangular prism has an incidence surface8, to which the illumination light is applied at right angles. The illumination light is applied to the interface22between the optical member7and the holographic stereogram6, at an incidence angle θ of, for example, 60°, thereby to suppress surface reflection of the illumination light9at the interface22.
