Apparatus for converting optical information into electrical information signal, information storage element and method for storing information in the information storage element

摘要

An apparatus for converting optical information into an electrical information signal includes a plurality of one-dimensional conversion arrays arranged in parallel form. Each one-dimensional conversion array has first and second photoelectric conversion structures integrally formed. The first photoelectric conversion structure has photoelectric conversion elements each having a light receiving surface onto which an information light is projected. The second photoelectric conversion structure has photoelectric conversion elements each having a sweep light receiving surface onto which a sweep light is projected. The sweep light has a cross section which simultaneously scans the sweep light receiving surface of one of the photoelectric conversion elements included in each of the one-dimensional conversion arrays. The electrical information signal is read out from the photoelectric conversion elements provided in the first photoelectric conversion structure when the sweep light is projected onto the photoelectric conversion elements provided in the second photoelectric conversion structure.
