A light source unit(11) cuts off and transmits beams and expands widths of transmitted laser beams under control of the control unit(10). A beam splitter(12) optically splits the laser beams of which the widths are expanded into an object beam and a reference beam. An object beam processing unit(13) cuts off or transmits the object beam, generates point holograms for all coordinates in the virtual space by spatially modulating the transmitted object beam, and then records the object beam in the photorefractive recording medium(15) by reducing the object beam to have a recordable beam width, under control of the control unit(10). A reference beam processing unit(14) varies the reference beam when recording the point holograms in the photorefractive recording medium(15) to have a different incident angle. A display unit(1) enlarges the holograms recorded in the optical photorefractive recording medium(15) to an observable size.
