Abstract

PURPOSE:To obtain the reconstructed image of linear plane scanning simply and easily by reconstructing the holograms made while displacing both or only one of an object light source and a reference light source in prescribed functional relations in association to the rotation of photosensitive materials for holograms with a stationary reference light. CONSTITUTION:An object light source 21 and a reference light source 22 have independent fine adjustment mechanisms such as linear motors, voice coils and the like. In manufacturing holograms, a disc 3 incorporated with flat plate photosensitive materials 301, 302- for holograms is rotated slightly each time, and in association to this rotation, the respective fine adjustment mechanisms are driven to move the light sources 21, 22, thereby changing the incident angle or distance to the photosensitive material for holograms 301- simultaneosly or one of them. The displacements of the light sources 21, 22 and the rotation of the disc 3 has a constant functional relation, so that the reconstructed image by reconstruction light 5 makes linear plane scanning on a plane 4. Thereby, the reconstructed image of the linear plane scanning is easily obtained.
