Abstract
This paper proposes a new two-way data communication system for vehicles using laser and corner cubes. This system is useful for data communication between vehicles on the road or between vehicles and terminals over the road; and is composed of laser transceivers and respondent devices to realize two-way communication using only one optical laser source. Two types of respondent devices are proposed. One is a respondent device consisting of laser receivers and optical modulators using corner cube prism and piezoelectricity cell, the other is a respondent device consisting of laser receivers and optical modulators using corner cube reflectors and reflector controllers. Operation of two types of modulation are confirmed by experiments. New data communication system between vehicle-to-vehicle and vehicle-to-terminal over the road are also proposed.
