Abstract:
1. A system, comprising: a source of radiation configured to produce a beam of radiation; a first reference fiber including first and second ends, the first end being configured to receive the beam of radiation and the second end being spaced from a sample; sensing fibers respectively including plasmon sensors having corresponding various shapes, each of the sensing fibers are configured to receive the beam of radiation and be in contact with the sample; additional reference fibers, each of the additional reference fibers having a plasmon sensor of a shape corresponding to a respective one of the sensing fibers, each of the additional reference fibers is configured to receive the beam of radiation, and each of the additional reference fibers is spaced from the sample; reference detectors configured to sense outputs from the first and the additional reference fibers; and sensing detectors configured to sense output from the sensing fibers.
