目前,光导纤维技术在电子通讯系统中,用于传输数据已是很普通的事了。但是将光导纤维技术用于工业生产过程的压力、液位、流量、振动的变送以及气体组分含量、气体泄漏检测报警等,还是一项刚刚起步的新技术。正是由于光导纤维技术在仪器仪表领域中具有广阔的应用前景,因此近几年来,国外工业发达国家,特别是美国、日本 Currently, optical fiber technology in the electronic communications system, used to transmit data is very common thing. However, the optical fiber technology for industrial production process pressure, liquid level, flow, vibration transmission and gas content, gas leak detection alarm, or just a start of new technology. It is because of optical fiber technology in the field of instrumentation has broad application prospects, so in recent years, foreign industrialized countries, especially the United States, Japan
