REFLECTIVE COLLECTION-TYPE LIGHT RECEIVING UNIT AND LIGHT RECEIVING APPARATUS FOR SPATIAL LIGHT COMMUNICATIONS

摘要

PURPOSE: A light receiving unit of a reflective light collection-type and a light receiving apparatus for spatial light communication are provided to shorten thickness dimensions of a main body, thereby miniaturizing the light receiving unit of a reflective light collection-type. CONSTITUTION: A light receiving device(3) faces a reflecting surface side(2a) of a concave mirror(2) in a center portion inside the concave mirror. A pair of electrode leads(4,5) are connected to both electrodes of the light receiving device. The electrode leads are extended to open toward both side portions of the concave mirror from the center portion of the concave mirror. The electrode leads are connected to a light receiving circuit through an outer surface of the concave mirror. The light receiving device receives spatial light. The light receiving device outputs a generated light receiving signal to the light receiving circuit through the electrode lead.
