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).

摘要： A multiple hologram recorder includes an optical system and an incident angle controller. The optical system applies a recording beam and a reference beam to a unit recording region of a hologram recording medium. The recording beam is modulated in accordance with information to be recorded. The reference and the recording beams have the same wavelength. The angle controller adjusts the incident angle of the recording or reference beam to preset angles. Every time the incident angle is adjusted to one set angle, one-page holographic recording is performed. The set angles include a reference angle associated with an angular interval. The incident angle controller causes the incident angle to continuously vary within the angular interval when the incident angle is adjusted to the reference angle. This continuous variation is performed with the recording and the reference beams irradiating the unit recording region.

摘要： A hologram recorder is provided, in which coherent light from a light source is split into a signal beam and a reference beam, and the signal beam is modulated by a spatial light modulator to be directed to a hologram recording medium, while the reference beam is directed to the hologram recording medium to overlap with the signal beam for recording a hologram on the hologram recording medium. The hologram recorder includes a beam phase modulator provided with a plurality of optical devices (20p, 20p′) each configured to assume one of two modes such as ON mode and OFF mode, the ON mode for causing the reference beam to be passed or reflected in a predetermined direction toward the hologram recording medium, the OFF mode for causing the reference beam to be blocked or directed in another direction other than the predetermined direction. Each optical device (20p, 20p′) provides a phase difference 0 or π. A phase modulation controller is also provided for individually controlling the optical devices (20p, 20p′) to cause each of the optical devices to assume the ON mode or the OFF mode, thereby modulating the reference beam into a beam having a predetermined phase pattern.
