摘要： Method for producing a of a transparent type hologram screen of an wide visible range. 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 method for producing a hologram recording an interference fringe formed by an object light and a reference light on a photosensitive dry plate, and the object light either having diffusing and scattering characteristics or being passed through an optical diffusion body, mainly includes the following steps: In a first step, a ratio .eta..sub.R0 /.eta..sub.00 of a first diffraction efficiency .eta..sub.00 and a second diffraction efficiency .eta..sub.R0, is calculated. The diffraction efficiency .eta..sub.00 is dependent on two object light beams. The efficiency .eta..sub.R0 is dependent on the object light and the reference light. In a second step, the intensity E.sub.O of the object light and the intensity E.sub.R of the reference light is adjusted in such a way that the ratio .eta..sub.R0 /.eta..sub.00 is set to at least 10 and the efficiency .eta..sub.00 does not exceed 5%.A display device using the above hologram is structured by a display unit for generating a signal light; a hologram screen formed by either reflection or transmission hologram, and a projecting unit for projecting the signal light to the hologram screen.According to the present invention, it is possible to easily produce a hologram, for example, a screen hologram, having no cloudiness or cloudy state when an observer observes an image displayed on the screen, and to a display device using the above hologram screen.

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.
