Abstract

A holographic storage system includes a light emitter, a spatial light modulator, a first reflector, a light guide module, and an actuator. The light emitter is used for providing at least one light beam. The spatial light modulator is used for receiving and modulating the light beam from the light emitter. The first reflector is optically coupled between the spatial light modulator and the lightguide module, and the light guide module is used for guiding the light beam reflected from the first reflector to the storage disc and guiding the light beam exiting from the storage disc to the lightdetector. The first actuator is connected with the first reflector and used for enabling the first reflector to rotate and translate. The state of the first reflector is adjusted through the first actuator, the optical detector can be prevented from reading distorted signals, and therefore the signal reading efficiency of the holographic storage system is improved.

Description

technical field [0001] The present invention relates to a holographic storage system. Background technique [0002] With the development of technology, the required storage capacity of electronic documents also increases. A common storage method is to record the magnetic or optical changes on the surface of the storage medium as the basis for the stored data, such as a magnetic disk or an optical disk. However, as the amount of storage required for electronic documents increases, technological developments in holographic storage have begun to receive attention. [0003] Holographic storage technology writes image data into a storage medium (photosensitive material) after signal light and reference light interfere. When reading the data, the image data can be generated by re-irradiating the reference light onto the storage medium (photosensitive material). Then, the generated image data is read by the photodetector. However, when reading, the disc containing the storage m...
