ABSTRACT:
A system for measuring an index of refraction that has a light emitting diode and a plurality of reference fibers not in contact with a sample to be measured and that receive light from the light emitting diode. A plurality of sensing fibers with different-shaped plasmon sensors are in contact with the sample and receive light from the light emitting diode. Detectors sense an output of the light from the fibers. The sensing fibers can be arrayed in a planar arrangement, or in a bundle. A cylindrical lens can be used for directing light into the fibers. A plurality of light emitting diodes can be used, each directing its light output into a corresponding fiber. A ball lens can be used for directing the light into the reference fiber. A plurality of wavelength filters can be placed between the light emitting diode and the sensing fiber, and a wavelength of the light entering the fiber may be selected using the filters.
