Abstract
A holographic optical accessing system includes a light source for emitting a light beam; an optical assembly module for receiving the light beam and generating a signal beam and a reference beam that are parallel to each other rather than overlap with each other, and have the same first polarization state; a lens module for focusing the signal beam and the reference beam on a focal point at the same time; and a storage medium for recording the focal point. The optical assembly module includes at least a data plane for displaying image information so that the signal beam contains the image information.
