Abstract

See full text

An optical transmission unit (3) transmits an optical signal having a light intensity set as a Low level component of a pulse. An optical partial reflector (6) is provided on a path through which transmission light is transmitted from a circulator (5) to the atmosphere, and reflects the optical signal. A detection unit (11) performs coherent detection on reception light using, as local light, a signal in a Low level section in the optical signal reflected by the optical partial reflector (6).
