前言供通信应用的光纤系统在10年前就开始走出实验室而进入实际应用。1975年,全世界光纤通信元件的产值约为250万美元。在过去十年间,光纤通信元件的使用量增加了800多倍,1985年全世界光纤元件的价值约达20亿美元。相比之下,光纤传感器还刚刚起步。虽然在过去十年内,光纤传感技术一直在发展,并在实验室样机方面已取得显著进展,但在1985年,全世界供实用的传感器产值只有880万美元。光纤传感器的稳定增长将归于下列因素的推动。·光纤元件性能的不断提高,由于它们
Introduction Fiber optic systems for communications applications began to go out of the lab 10 years ago for practical applications. In 1975, the world’s optical fiber communications components output value of about 2.5 million US dollars. The use of optical fiber communication components has increased more than 800-fold in the last decade, and the value of optical fiber components in the world in 1985 has reached about 2 billion U.S. dollars. In contrast, optical fiber sensors have just started. Although fiber-optic sensing technology has been evolving over the past decade and significant progress has been made in laboratory prototypes, in 1985, the world’s actual sensor output was only $ 8.8 million. The steady growth of optical fiber sensors will be attributed to the following factors. The performance of fiber optic components continues to improve due to them
