High temperature fiber optic strain sensing
(Virginia Tech, 1991-05-15)
<p>Two high temperature fiber optic based strain sensors have been developed for use
in a coal combustor environment. An intensity based sensor uses losses created
by longitudinal misalignment as a sensing mechanism and ...
Longitudinal misalignment based strain sensor
(Virginia Tech, 1989-06-04)
<p>A practical fiber optic strain sensor has been developed to measure strains in the
range of 0.0 to 2.0 percent strain with a resolution ranging between 10 and 100
microstrain depending on sensor design choices. This ...
Increasing the survivability of long distance fiber optic networks
(Virginia Polytechnic Institute and State University, 1989)
Automated infrared fiber optic characterizer
(Virginia Polytechnic Institute and State University, 1989)
Fiber-optic sensors for weigh-in-motion application
(Virginia Polytechnic Institute and State University, 1989)
Automated techniques to acquire weight and traffic data are indispensable to effective management and maintenance of the vast network of highways. Weigh-In-Motion (WIM) systems have the potential to greatly reduce the cost ...
Axial offset effects upon optical fiber sensor and splice performance
(Virginia Polytechnic Institute and State University, 1985)
A kind of intensity modulated fiber sensor utilizing axial offset parameter is proposed. The theoretical analysis and experimental characteristics of this sensor are described.
All the theoretical results derived in this ...
