Opto-mechanical Fiber Optic Sensors

Book Description

Opto-mechanical Fiber Optic Sensors: Research, Technology, and Applications in Mechanical Sensing offers comprehensive coverage of the theoretical aspects of fiber optic sensors (FOS), along with current and emerging applications in the mechanical, petroleum, biomedical, biomechanical, aerospace and automotive industries. Special attention is given to FOS applications in harsh environments. Due to recent technology advances, optical fibers have found uses in many industrial applications. Various sectors are major targets for FOS's capable of measuring mechanical parameters, such as pressure, stress, strain and temperature. Opto-mechanical FOS's offer unique advantages, including immunity to electromagnetic interference, high fidelity and signal-to-noise ratio, low-loss remote sensing and small size.

  • Provides current background information and fundamentals on fiber optic sensors technology
  • Covers a wide variety of established and emerging applications of FOS
  • Focuses on mechanical parameter measurement
  • Includes contributions from leading researchers and practitioners in their fields
  • Covers current methods of fabrication and packaging
