光纤是二十世纪的技术奇迹之一。它使现代高速通信网络成为可能，这一重大贡献得到了高锟的认可，并于 2009 年荣获诺贝尔物理学奖。然而，大多数公众不知道的是，光纤技术也为传感器和成像技术做出了重大贡献。在光纤开发的早期阶段，人们认识到具有小直径、极长长度和柔性的光纤具有开发内窥镜成像装置和传感器所需的特性。较长的光纤长度使得光纤传感器具有较长的相互作用长度，从而使其具有很高的灵敏度。小直径使得光纤传感器和成像仪变得紧凑和便携。灵活性使得传感器和成像仪可以放置在最狭窄的空间中。现在，光纤成像和传感设备被广泛应用于医疗、环境、制造和国防等领域。本书旨在重点介绍光纤成像和传感设备的基本原理。这本书绝不是完整和全面的。但它旨在为读者提供光纤成像和传感设备方面的坚实基础。它首先是从麦克斯韦方程组开始的介绍性章节，主要是为了向读者展示光纤器件中的控制方程从何而来，以及如何推导它们的一些想法。本章最后推导了基本光纤特性方程和解（即光纤模式）。第 2 章回顾了最常见的光纤干涉测量设备，它们是许多光纤成像和传感系统的基础。第 3 章讨论光纤成像仪的基础知识，重点介绍光纤共焦显微镜。光纤干涉传感器在第 2 章中详细讨论。 4 和 5。第 4 章讨论基于光纤布拉格光栅的传感器和各种应用。第 5 章详细介绍了基于 Sagnac 环路的光纤传感器。第 6 章详细介绍了光学相干断层扫描。与其他章节不同，它详细介绍了实时 OCT 实现的信号处理和系统级方法，我希望读者会发现这些对构建自己的 OCT 系统有用。所有章节都从器件特性的理论推导开始。这是为了帮助学生读者理解 v
Optical fiber is one of the twentieth century’s technology marvels. It made the modern day high-speed communications networks possible and this significant contribution was recognized by Charles K. Kao being awarded the Nobel Prize in Physics in 2009. However, unknown to most of the general public, optical fiber technology has made significant contributions to sensors and imaging technologies as well. It was recognized during the early part of the optical fiber development that optical fibers having small diameter, extremely long length, and flexibility have desired properties for developing endoscopic imaging devices and sensors. The long fiber length allowed the fiber optic sensors to have long interaction lengths which made them highly sensitive. The small diameter allowed the fiber optic sensors and imagers to be made compact and portable. The flexibility allowed the sensor and imagers to be placed in most tight spaces. Now, fiber optic imaging and sensing devices are being used for a wide range of applications such as in medical, environmental, manufacturing, and defense. This book is designed to highlight the basic principles of fiber optic imaging and sensing devices. The book is by no means complete and comprehensive. But it is designed to provide the readers with a solid foundation in fiber optic imaging and sensing devices. It begins with an introductory chapter that starts from Maxwell’s equations, mostly to show the readers where the governing equations in fiber devices come from and some idea as to how they are derived. The chapter ends with the derivation of the basic optical fiber characteristic equations and solutions (ie, fiber modes). Chapter 2 reviews most common fiber optic interferometric devices which are bases for many fiber optic imaging and sensing systems. Chapter 3 discusses the basics of fiber optic imagers with emphasis on fiber optic confocal microscope. The fiber optic interferometric sensors are discussed in detail in Chaps. 4 and 5. Chapter 4 deals with fiber Bragg grating based sensor and various applications. Chapter 5 goes over in detail fiber Sagnac loopbased sensors. Chapter 6 covers optical coherence tomography in detail. Unlike other chapters, it goes into details the signal processing and systems level approach of the real-time OCT implementation that I hope the readers may find useful for building their own OCT systems. All the chapters start with theoretical derivation of devices characteristics. This is to help student reader with understanding the v
