SPIE - Education Optical Fiber Sensing Technology: Basic Principles & Applications in Defense and Security SC945

This course describes optical fiber sensing principles and technology, as well as the associated specialty fiber types and components required for their system integration. A broad overview of diverse applications is made with a particular emphasis on defense and security. Key fiber sensing solutions will be reviewed including the usage of the Sagnac interferometer (fiber optic gyro—FOG) for guidance and control; acoustic detection and distributed sensing (using interferometric as well as Rayleigh, Raman and Brillouin scattering techniques) for underwater intrusion detection, littoral monitoring and perimeter security; fiber Bragg gratings (FBGs) for localization and identification of damage—in vessels and aircraft—and for bio-chemical agent detection. Other relevant fiber sensors and applications in non-defense applications such as oil & gas, civil structures, energy, will be described as well.
