Fiber optic sensing measures changes in the naturally occurring “backscattering” of light occurring in an optical fiber (or designed in methods of controlled reflection such as Fiber Bragg Gratings). Measurable change is observed when the fiber encounters vibration, strain or …
FOSA – Fiber Optic Sensing Association
The Fiber Optic Sensing Association (FOSA) is dedicated to accelerating the use of distributed and quasi-distributed optical fiber sensing technologies. Fiber optic sensing works by measuring changes in the “backscattering” of light occurring in an optical fiber when the fiber encounters vibration, strain or temperature change.
About Us - FOSA
The Fiber Optic Sensing Association’s mission is to educate industry, government and the public on the benefits of using advanced optical fiber based sensing technologies to enhance public safety, promote security of critical facilities and infrastructure, and protect the environment.
Distributed Strain Sensing (or DSS) is a fiber-optic sensing technology providing spatially resolved elongation profiles along a fiber-optic sensing cable. By combining multiple sensing cables at different positions in the asset cross-section, DSS is used to compute the asset
Distributed Acoustic Sensing (DAS) is a sensing technology that delivers real time spatially resolved acoustic and vibration output from virtually unlimited points along a fiber optic cable. The technology effectively turns common optical fiber (or specially optimized cables) into a series of thousands of sensitive virtual microphones
what is fiber optic sensing? Distributed and quasi-distributed fiber optic sensors are systems that connect opto-electronic interrogators to an optical fiber (or cable), converting the fiber to an array of distributed sensors.
WHAT IS Distributed Temperature Sensing? Distributed Temperature Sensing (DTS) is a fiber-optic sensing technology for measuring spatially resolved temperature profiles along fiber-optic sensor cables. Sensor cables may be installed near linear assets as well as on 2- or 3-dimensional objects for measuring their temperature profiles. HOW DOES ...
