Optical Circulators and Gratings
An optical circulator is a three- or four-port designed such that entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but. What is a Faraday Circulator? Figure 1: Symbol for a three-port Faraday circulator.

How to measure strain using fiber Bragg gratings
This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which enables strain gages and FBGS to be measured simultaneously, providing all data processing functions originally developed. The work is devoted to the consideration of methods for determining the strain of objects using fiber Bragg gratings under a high-frequency vibration or pulsed mechanical action, which is difficult to perform using widespread methods and devices. A fiber Bragg grating is a small length of optical fiber that comprises a pattern of many reflection points that creates a reflection of particular wavelengths of incident light.

Methods for Detecting Stress in Fiber Bragg Gratings
This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which enables strain gages and FBGS to be measured simultaneously, providing all data processing functions originally developed for the. Fiber Bragg Grating Sensors (FBGS) are gaining increasing attention in the field of experimental stress analysis. They are easy to install, immune to electromagnetic interferences and can also be used in highly explosive atmospheres.
