EAST Knowledge invites you to attend our fifth meeting!
* **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. |
