Abstract: A sweep sensor may include a signal source, a propagation medium, and a detector. By transmitting an interrogating signal from the signal source into the propagation medium, detectable disturbances along the medium can physically alter the characteristics of the medium, which may cause a measureable change in the backscattered signal at the detector. Based on the change, it may be possible to locate the geographic origins of the physical disturbances along the propagation medium, or to determine the nature of the disturbances, or both. For example, it is generally possible to estimate the approximate distance between the detector and the disturbance given the time required to obtain the backscattered signal and the velocity of the signal source in the propagation medium. Further, in some embodiments, it is possible to quantify the amount of disturbance.

Abstract: An optical polarization encoding been invented which allows wavelength dependent processing of polycromatic opticals without prior separation into narrow wavelength bands. The invention comprises a stack of variable and fixed birefringent elements which introduces, on passage though the stack, wavelength dependent polarization onto a polycromatic optical signal of arbitrary polarization. Desired polarizations are achieved simultaneously at all wavelengths contained within the incoming signal by independently varying the birefringence and/or crystallographic orientation of each element within the stack. The encoded signal may be subsequently be processed, e.g. rerouted or attenuated, as a function of wavelength using polarization dependent devices. The encoding stack is rendered polarization insensitive by dividing the incoming optical signal, with a polarization beam splitter, into two beams of orthogonal polarization prior to passage through the stack.
