Optical two-way communication system for vehicles using lasers and corner cubes

This paper presents a new two-way data communication system for road vehicle control using laser beams and corner cubes. This system shows good performance for data communication between vehicles on the road or between vehicles and terminals over the road. This system uses laser transceivers and respondent devices to realize two-way communication. The respondent device consists of laser receivers and optical modulators using corner cube prisms and piezoelectric cells. The operation principle of this system is confirmed by experiments.
