HOLOGRAM-REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a hologram-reproducing device capable of accurately reproducing the hologram data which is multiply recorded by a shift multiplexing system in a hologram recording medium.

SOLUTION: A two-dimensional image sensor 21 is switched by an electronic shutter to start/stop capturing of the reproduced light. A timing signal generator 51 generates an electronic shutter signal determining a shutter timing of the electronic shutter, by using a luminance signal from a photodetector 23 that receives a part of the reproduced light obtained by irradiating a hologram recording medium 100 with reproducing reference light.
