FBG Sensor Module Performance Estimation

LEOS 2007 - IEEE Lasers and Electro-Optics Society Annual Meeting Conference Proceedings, 2007
A method to estimate FBG sensor module performance is presented. Both temperature effect and stress effect on bare and packaged FBG sensors have been addressed theoretically and experimentally with good agreement.

FBG hydrophone: Theory and experiment

2008 1st Asia-Pacific Optical Fiber Sensors Conference, 2008
A fiber Bragg grating (FBG) hydrophone with enhanced sensitivity is demonstrated. A novel piston-like diaphragm with a hard core fixed at the center is used as the sensing element. Theoretical analysis shows that the Young's modulus of the diaphragm and the radius of the hard core have significant effect on the pressure sensitivity.

Tunable FBGs for wavelength scanning

2015 Photonics North, 2015
We demonstrate a low-cost tunable fiber Bragg grating (FBG) filter using electromagnetic tuning. Continuous wavelength scanning feature of this filter is evaluated by incorporating the same into a fiber laser system.

High reliability FBG interrogation analyzers

SPIE Proceedings, 2009
The invention of optical fiber and semiconductor lasers in the 1960s opened up a cornucopia of applications, notably as a medium of carrying light signals for communications and sensing applications. Optical fibers provide a fundamental improvement over traditional methods offering lower loss, higher bandwidth, immunity to electromagnetic ...
