摘要: A holographic ROM system includes a light source (200) for emitting laser beam; an expanding unit (204) the and mask (206) modulating certain portion of expanded beam to thereby generate signal which is directly provided medium (208) sifting remainder reference conical mirror (210) reflecting toward medium. The composed recording region onto both are projected; transparent passes through sifted by mask, provide mirror.
