PROBLEM TO BE SOLVED: To provide a communication device that is simple to install in a vehicle and efficient in transmission of information between vehicles.SOLUTION: The communication device includes a transmission system (1) equipped with a light source (2) designed to emit an initial light beam (3). The transmission system (1) is configured for generating a first light beam (4) polarized in a first direction (7) starting from the initial light beam (3). The transmission system (1) further includes a modulator (11) of the direction of polarization of the first polarized light beam (4) in order to transmit information. The device further includes a receiver system configured for detecting the first polarized light beam when the first polarized light beam (4) is polarized in the first direction (7) and for transmitting the information.SELECTED DRAWING: Figure 1

    【課題】車両内への取り付けが簡単であり、かつ、車両間の情報送信が効率的である通信装置を提供する。【解決手段】通信装置は、初期光ビーム(3)を発するように設計された光源(2)を備えた送信システム(1)を備える。送信システム(1)は、初期光ビーム(3)から始まる、第1の方向(7)に偏光された、第1の光ビーム(4)を生成するように構成される。送信システム(1)は、情報を送信するために、第1の偏光ビーム(4)の偏光方向の変調器(11)をさらに備える。第1の偏光ビーム(4)が前記第1の方向(7)に偏光されている場合に、この第1の偏光ビームを検出し、かつ、前記情報を送信するように構成された受信システムをさらに備える。【選択図】図1
