Optical Fiber Sensors

Preface

In the past several decades since the invention of the laser in 1960 and the development of modern low-loss optical fibers in 1966, optical fiber technology has made a transition from the experimental stage to practical applications. The main focus of the development of optical fiber has always been on telecommunications, but the early 1970s saw some of the first experiments on low-loss optical fibers being used for sensor purposes. The field of optical fiber sensing has continued to progress and has developed enormously since that time. Magnetic, pressure, temperature, acceleration, displacement, fluid level, current, and strain optical fiber sensors were among the first types extensively investigated and explored for sensing and measurement. ...
