EAST Knowledge is excited to announce it's fifth meeting. Jim Rulla will be giving a talk about how fiber optics can be used as sensors for locating intrusions. Come and learn something new! Come and share what you know! All are welcome!

|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.
