Patent ID: 6852452

Claim:
A method of fabricating a hologram screen, comprising: preparing a plurality of mirrors to be arranged at an end portion of a light diffuser and to be arranged at a side of a light source of a reference beam, each of said plurality of mirrors being extended toward each of a plurality of photosensitive members, respectively, such that a reference beam generated from the light source reaches said each of said plurality of photosensitive members without being shielded by said each of said plurality of mirrors; forming a plurality of holograms by successively exposing said each of said plurality of photosensitive members individually using said reference beam and a plurality of object beams passed through said light diffuser; and two-dimensionally arranging and integrating a plurality of said holograms thereby to form a hologram screen, wherein, in said successively exposing said each of said plurality of photosensitive members, one of said plurality of mirrors is replaced with another of said plurality of mirrors having a different length of extension from said light diffuser in accordance with the position of said each of the plurality of photosensitive members to be exposed individually thereby to expose said each of the plurality of photosensitive members without being shielded by the each of the plurality of mirrors.
