Abstract
According to one aspect, a holographic storage system including micro-actuators is presented. In one example of one aspect of the invention, the device includes a spatial light modulator, a detector, a storage medium, and at least one micro-actuator configured to move at least one of the spatial light modulator, the detector, and the storage medium. The micro-actuators may include a servomechanism or the like to control the positioning of a component based on feedback associated with a misalignment of a detected image. According to another aspect of the invention, various methods for determining component misalignments of a holographic storage system are presented.
