摘要： A hologram reproducing device includes a splitter for splitting a reference beam, during reproduction, into a main beam and sub-beams forming incidence directions spatially shifted from the main beam. The hologram reproducing device also includes: an incidence direction variable irradiator for changing the incidence directions of the main beam and the sub-beams; a servo beam detector for detecting a portion of the reproduction beam generated in accordance with the sub-beams; and a beam receiving unit for receiving the main portion of the reproduction beam generated in accordance with the main beam. A reproducer reproduces an image obtained by the beam receiving unit when the main beam coincides with the incidence direction at which the received light of the beam receiving unit becomes equal to or greater than a prescribed level, with the intensity of the reference beam kept uniform, on the basis of the servo beam detection results.

摘要： A hologram recorder applies a recording beam (S) and a reference beam (R) to the illumination site (p) of a hologram recording medium (B). The interference between the recording beam (S) and the reference beam (R) produces multiple hologram recording at the illumination site (p). The recorder includes a recording-purpose reference beam reflector (10) for reflecting the reference beam (R) to the illumination site (p), and a pivot mechanism for pivoting the reflector (10) about an axis (x) to vary the incident angle (θr) of the reflected reference beam (R) to the recording medium (B). The reflector (10) is disposed to cross a predetermined optical path. The axis (x) of the pivot mechanism is so arranged that the reflected reference beam (R) is directed to the illumination site (p) even when the incident angle (θr) of the beam (R) changes due to the pivoting of the reflector (10).
