Fiber Sensors Go 3-D
Optical fibers make ideal physical sensors. Light, rugged and immune to interference from stray electrical signals, they respond to a variety of external stimuli – qualities that have spawned extensive efforts to use them for measuring, or “sensing,” physical attributes such as temperature, strain and pressure. They are used for temperature monitoring in oil and gas “down hole” and applications, strain and fatigue monitoring in civil structures (dams, bridges) and buildings, strain measurement...
