Fiber Bragg grating-based acceleration sensor

2009 International Symposium on Optomechatronic Technologies, 2009
We present the design process of a fiber Bragg grating based fiber-optic single-axis acceleration sensor with minimized crosstalk. Crosscoupling of non-directional accelerations is minimized by introducing a unique double-membrane fixture of the sensor's mass of inertia leading to an almost diagonal form of the sensors stiffness-matrix.

Fiber Bragg Grating Based pH Sensor

AIP Conference Proceedings, 2011
In environmental or safety monitoring, continuous on-line systems are generally desired and fiber optic sensor (FOS) networks are well-suited for this purpose, with capability for large area coverage. The advantages of FOS are freedom from electromagnetic interference, wide bandwidth, compactness, and geometric versatility.

Fiber Bragg grating sensors

2010
A brief overview of fiber Bragg grating based sensor technology from sensor head, read out unit and commercial applications is given. Fiber Bragg grating based sensor systems are becoming mature rapidly. Components for commercial pressure sensors and temperature sensors are available and slowly getting accepted.

Distributed temperature fiber Bragg grating sensor

SPIE Proceedings, 2008
We propose a temperature measurement system based of fiber Bragg grating (FBG). FBG is applied as a sensor element, and a measurand is controlled in the finite number of points. For temperature registration and control of FBG reflection spectrum shift due to applied strain each sensor is tuned to a certain field of measured parameters.

Multipoint Sensor using fiber Bragg Gratings

Frontiers in Optics 2011/Laser Science XXVII, 2011
FBG-based sensors usually employ the spectral shift of Bragg wavelength to determine a physical variable magnitude. In this work, a multipoint sensor system that does not require spectral analysis to evaluate such variable is presented.

Fiber Bragg Grating Wireless Sensors Network

2008 4th International Conference on Wireless Communications, Networking and Mobile Computing, 2008
We demonstrate a novel wireless sensors network available for multi-dimension and multi-parameter measurement based on fiber Bragg grating sensing units. The combination of wireless communication with the fiber Bragg grating sensors obtains obvious advantages including inherent immunity to electromagnetic interference, compact size and high sensitivity

Fiber Bragg grating underwater acoustic sensor

13th International Conference on Optical Fiber Sensors, 1999
An underwater acoustic sensor with fiber Bragg gratings can detect a real-time waveform and thereby amplitude and phase of an acoustic field, which in turn allows directive detection of the field with an arrayed structure.

Applications of Fiber Bragg Grating Sensors

2012
The basic concepts and fabrication of optical FBG-based strain, directional force or pressure, and shear force sensors have been presented in Chapter 11. It is noted that the response to external stimulus is non-linear when direct sensing technique is applied to the FBG.

Fiber Bragg grating impulsive pressure sensor

SPIE Proceedings, 2005
A new impulsive pressure sensor based on the elastic bar, is presented in this paper. As the elastic bar a piece of single mode optical fiber with photo-inscribed Bragg gratings is used. The grating is an optical strain gauge that converts the stress waves in the fiber into the changes of the Bragg wavelength. Experimental setup for the proposed sensor
