Optical fiber sensing

Course title

1M991300

Course content

Today, the data transmission with high speed and large capacitance has been realized through optical communication systems, and one main component of the system is optical fiber. However, optical fibers are used not only for telecommunications but also for sensor applications. In this course, various physical phenomena in optical fibers and their sensing principles will be discussed while considering the state-of-the-art optical techniques.

Purpose of class

The purpose of this course is to help students to understand fundamentals of optics and how they are utilized in optical fiber sensing. This course also helps students acquire ability to apply the knowledge of optics to various fields including the specialized field of the student's self.

Goals and objectives

Being able to explain the basic concept of optical fiber sensors and their application to society.
Being able to explain various physical phenomena in optical fibers and its sensing principles.
Being able to utilize the technical knowledge of optics in their own specialty.
