Abstract
Systems and methods for detecting a change in at least one physical parameter of a target illuminated by electromagnetic radiation are disclosed herein. The system includes one or more optical fibers, an optical switch, and a photo detector. The optical fiber switch can transmit at least a portion of the electromagnetic radiation into the one or more optical fibers. The optical fibers can have a plurality of sensor nodes. The sensor nodes can induce an interaction between the change in the at least one physical parameter and the transmitted electromagnetic radiation to generate an optical signal. The photo detector can be connected to the one or more optical fibers and measure the optical signal.
