Claims

[Scope of utility model registration request]

An optical signal transmission device that sends a light beam output from one light emitting source to a far away corner cube, and sends the reflected light beam parallel to the incident light beam to the light emitting source side. a first modulator that modulates the light beam output from the source and sends it to the corner cube; and a first splitter that is disposed in front of the modulator and reflects the reflected light beam from the corner cube side at a predetermined angle. a first demodulator that demodulates the light beam reflected by the splitter; and a first demodulator that is arranged in front of the corner cube and modulates the reflected light beam using a modulation signal from the corner cube side and sends the modulated light beam to the light emitting source side. a second splitter that is provided in front of the modulator and splits a part of the light beam sent from the light emitting source via the first modulator; and a second demodulator that demodulates the emitted light beam, and performs bidirectional simultaneous communication using one light emitting source.
