摘要： A hologram of an increased size using a single color laser, capable of executing a full color regeneration in a desired view angle and a method for producing the hologram. A plurality of photo-sensitive members are independently exposed to obtain respective holograms, which are connected by using an adhesive layer 80 constructing a connecting means, in order to obtain an integrated hologram expanded in two-dimensional direction. The holograms are obtained by an interference of a reference light 22 and an object light passed through a light diffusing body 24 in order to cause the light diffusing body 24 to be recorded on the photo-sensitive member. The size of the light diffusing body 24 is such that the spectral characteristic of the diffused light from the hologram can attain a desired efficiency at least over the entire wavelength range of the visible light.

A photosensitive member and a light source of a reference light are arranged on the same side of the light diffusing body. A light source of an object light is arranged on the opposite side of the light diffusing body, so that the light is transmitted through the light diffusing body to generate a object light. A light from a light source of a reference light is reflected at the light diffusing body or a member such as a half mirror or a transparent, reflective hologram element arranged at a front side of the light diffusing body.

摘要： A hologram screen 1 displays an image by diffracting and scattering image light 31 projected from an image projection apparatus 2. An upward/downward light scattering device 13, which scatters light incident from an upward/downward specific angle range spreading obliquely upward or downward, is placed on the image projection apparatus side of a hologram device 12 in the hologram screen 1. A leftward/rightward light scattering device 14, which scatters light incident from a leftward/rightward specific angle range spreading obliquely leftward and rightward, is placed between the hologram device 12 and the scattering device 13. The construction is such that the upward/downward specific angle range contains the incidence angle of the image light 31 on the hologram screen 1, and thus provides a hologram screen having good color reproducibility and which permits viewing of the background.
