前言纤维光学是一门新技术,几年来在医疗与公共通信领域中取得了惊人的成就。一根像头发丝一样细的玻璃纤维可以传输上万路电话和几千道电视的幻想已变为现实。在美国,城市用光纤传输电话、电视很受用户欢迎;在日本,市内光纤电话系统已开始试用;英国、西德等国也都在进行类似的试验。由于光纤优越的物理特性,引起了广大科技界的普遍重视。尤其是它的体积小,重量轻,
Introduction Fiber Optics is a new technology that has made phenomenal achievements in medical and public communications over the years. The illusion that a thin fiber like hair wire can transmit thousands of telephones and thousands of televisions has become a reality. In the United States, cities use fiber-optic transmission of telephones and television is very popular with users; in Japan, the city’s fiber optic telephony system has begun trial; similar tests are being conducted in Britain, West Germany and other countries. Due to the superior physical properties of optical fiber, it has aroused widespread attention of the scientific and technological community. In particular, its small size, light weight,
