PROBLEM TO BE SOLVED: To provide a method of producing a hologram for allowing easy observation of a reproduced image. SOLUTION: The method of producing a hologram, which can reproduce the same image by respective light beams incident from at least two directions, includes a process for making laser beams individually generated by two or more laser sources 21a and 21b incident on a photosensitive material 13 at the same time to record interference fringes 11a and 11b. The respective laser beams generated in the two or more laser sources incident on the photosensitive material as object beams reflected by a model 7 of an image to be reproduced and as reference beams advancing in the direction different from that of the object beams. A plurality of object beams are incident on the photosensitive material from the same side mutually. A plurality of reference beams advance in the mutually different directions to be incident on the photosensitive material from the same side mutually. COPYRIGHT: (C)2011,JPO&INPIT |
