The Amazing Versatility of Fiber Optic Sensors – and the Micron Optics sm125 Interrogator

Published by at 4:22 pm under General

What do the following have in common:
- Measurement of huge strains of 20 to 40%
- Detection of 0.04 psi changes in hydrostatic pressure over a range of more than 13,000 psi
- Sensing of tiny electromagnetic fields with a resolution of 1 milliTesla

Answer:
1) Each are fiber optic sensors relying on fiber Bragg gratings and/or special high birefringence fibers
2) And each depend on the Micron Optics sm125 interrogator to achieve these results.

Since the initial release of the sm125 in 2004, it has become the mainstay for research, development, and deployment of fiber optic sensing solutions. Users can count on the internal NIST-traceable gas cell for accurate measurements on every sweep of the powerful laser. The sm125 has helped increase the pace of growth and acceptance of fiber optic sensors.

    Pls send me books/artricles/contents related to Fiber Optic sensors so that it can be useful for my research work.
