Analysis of ultrasonic frequency response of surface attached fiber Bragg grating
(Optical Society of America, 2012-07-01)
In recent years, fiber Bragg grating (FBG), for the well-known advantages over other fiber optic sensors, has attracted more attention in ultrasonic inspection for structure health monitoring (SHM). Spectrum shift of FBG ...
Modification Of Spontaneous Emission in Bragg Onion Resonators
(Optical Society of America, 2006-03-01)
We formulated an analytical model and analyzed the modification of spontaneous emission in Bragg onion resonators. We consider both the case of a single light emitter and a uniformly distributed ensemble of light emitters ...
Self-Compensating Fiber Optic Flow Sensor System And Its Field Applications
(Optical Society of America, 2004-07-01)
A self-compensating fiber optic flow sensor system based on the principle of broadband white-light interferometers and cantilever beam bending is described. The fiber optic sensor system uses two fiber ferrule sensors that ...
Minimum Detectable Phase-Shift in Spectrum-Analysis Techniques Of Optical Interferometric Vibration Detection
(Optical Society of America, 1992-11-01)
The minimum detectable phase shift indicated in recent experimental reports of new linear spectrum-analysis techniques of optical interferometric vibration detection is established as the direct consequence of the 1/f noise ...
