一、前言 70年代以后,着力研究开发通信用光纤来作为大量信息传递的手段,承担着信息时代的使命。随着光纤研究、开发的进展,其诸多的物理特性引人注目,由原来以光通信为目的而诱发派生出来了光纤敏感这样新的科学计测领域。 光纤敏感技术弥补了以铜线为主体的电计测的弱点,或者说它成了以电计测为主的种种计测手段和已有的计测领域的新的承担者,人们正在注视着它的发展动向。这种敏感技术大致分为两种:即利用光纤作信息传
I. Introduction Since the 1970s, efforts have been made to research and develop optical fiber for communications as a means of transmitting a large amount of information and assume the mission of the information age. With the development of optical fiber research and development, many of its physical characteristics attract attention, from the original purpose of optical communications derived from the optical sensitivity of such a new field of scientific measurement. Fiber-optic sensing technology makes up for the weakness of electrical measurement based on copper, or it is the new undertaker of all measurement methods based on electrical measurement and existing measurement areas. People are watching Its development trend. This sensitive technology can be broadly divided into two types: the use of optical fiber for information transmission
