ABSTRACT:
A hologram recording method wherein a transparent member for introducing a light beam into a recording material is designed so that the transparent member and the recording film can be uniformly brought into close contact with each other through an index matching liquid without damaging the recording film, and it is possible to stably carry out uniform and continuous exposure without failure of recording nor occurrence of unnecessary interference fringes. Also disclosed is a recorded hologram. A transparent member (3) is disposed at one surface of a recording film (2). A surface (5) of the transparent member (3) that is brought into close contact with the recording film (2) is convexly curved only in the direction of feed of the recording film (2). In addition, the space between the contact surface (5) and the recording film (2) is filled with an index matching liquid (4) so that the recording film (2) is brought into close contact with the transparent member (3) through the index matching liquid (4). In this state, a light beam is made incident on a surface (6) of the transparent member (3) other than the contact surface (5) so that the incident light beam reaching the recording film (2) through the contact surface (5) and the light beam reflected from the interfacial boundary between the reverse surface of the recording film (2) and the air interfere with each other in the recording film (2), thereby forming and recording interference fringes in the recording film (2).
