OPTICAL 2-WAY COMMUNICATION EQUIPMENT

摘要

PURPOSE:To send/receive a proper signal in 2-way and to eliminate the need for power transmission to a slave set even when a shade is formed in a spatial optical signal without need of setting the spatial optical signal route. CONSTITUTION:A master set and a slave set are provided respectively with a master set side optical signal reception section 7 and an individual set side optical signal transmission reception section 8 having a function of emitting a transmission signal as a spatial optical signal and having a function of processing a received transmission signal, in which lots of light emitting elements 11 are arranged so that emitting spread spatial optical signals are in duplicate with each other so as to reach a wide range of space, and lots of light receiving elements 10 are arranged so that the light receiving ranges of the elements 10 are in duplicate and one light emitting element 10 can receive the spatial light signals from the plural light emitting elements 11.
