Apr 18, 2015 		EAST Knowledge - Locating Intrusions Using Fiber Optics
– Gresham Library Story Room

EAST Knowledge invites you to attend our fifth meeting! All are welcome!

  • What: Locating Intrusions Using Fiber Optics
  • Who: Jim Rulla
  • Where: The Story Room at the Gresham Library
  • When: 10:30am-Noon, Saturday, April 18, 2015
  • Why: Sharing what we know

Interferometers measure distances to within fractions of the wavelength of light. Put a couple of these incredibly sensitive devices on the fence around an airport, and you can not merely detect a would-be intruder — you can locate him. Put a pair on a pipeline, and you can not merely detect nearby digging that could damage the pipe — you can locate its source. You might even be able to detect — and perhaps even locate — leaks in the pipe.

The detection and location mechanisms are fascinating examples of clever engineering. I'll explain how these patented systems work and illustrate new algorithms that improve performance.
