空間伝送方式。[Claims for Utility Model Registration] In a device that transmits signals by light using a light-emitting element and a light-receiving element, the light-emitting part has a means for outputting a transmission signal and its inverted signal using light with different optical parameters, The light receiving section includes means for differentially converting the transmission signal and its inverted signal transmitted by light having the optical parameters into electrical signals, and an in-phase component of the means for differentially converting into electrical signals. An optical space transmission system characterized in that an optical aperture is provided that is controlled so that the residual conversion of an external optical signal becomes zero by the output of the external optical signal.
