Method and apparatus for recording interference fringe pattern |
摘要 |
In order to record an interference fringe pattern in a recording layer of a medium, a plurality of laser beams are caused to interfere so as to form interference fringes in the recording layer; and during a time period over which the plurality of laser beams are caused to interfere, the following steps are continuously performed: (1) producing a signal varying according to a shift of a specific position in the recording layer; and (2) shifting a fringe-forming position in the recording layer by changing a phase of at least one of the laser beams or moving the recording layer based upon the signal produced in the step (1).
