Abstract
Distributed optical sensing systems utilize compressive sensing techniques to determine parameters sensed by a waveguide. The system generates light that is sent along a sensing waveguide, thereby producing backscattered light. A compressive sampling filter forms part of the system, and is used to selectively block portions of the generated light or the backscattered light. The backscattered light is received by a receiver and used to determine one or more parameters.
