Abstract
An optical system capable of selectively processing CD, DVD and holographic digital data is provided. The system includes a beam generation unit providing a linearly polarized light beam; a beam splitter for respectively reflecting and transmitting a first and a second linearly polarized light beam component; an optical sensor; a first beam path through which the first linearly polarized light beam component propagates to serve as a reference beam for the holographic digital data; and a second beam path for accepting the second linearly polarized light beam component, the second light beam component serving as a beam source for reproducing the CD and DVD digital data, wherein a beam carrying digital data reproduced from any one of CD, DVD and holographic storage medium propagates along the second beam path and is reflected by the beam splitter toward the optical sensor.
