摘要： A spectroscopic based optical fiber sensor includes a sensitive optical fiber, a probing light source, a power supply, a detector means, a signal processing means, and a display means. The sensitive optical fiber is optically affected by the presence of at least one measurand. The probing light source, adjacent to the sensitive fiber, transversely illuminates the fiber from the outside. The probing light is modified by the sensitive fiber, coupled into the optical fiber core, either as bound modes or leaky modes, as a light signal and guided to a detector means located at the terminus of the optical fiber. The detector means correlates the intensity of the light signal with an electric signal and transmits the electric signal to the signal processing means, wherein the electric signal is correlated to the quantity being measured. The correlated quantity being transmitted and displayed on the display means.

摘要： A side illuminated multi point multi parameter optical fiber sensor that requires no sensitive coating is provided. This sensor comprises an optical fiber having at least one removed cladding section as the sensitive region, at least one probing light source that side illuminates the fiber, a power supply, a detector, a signal processor and a display. The sensitive optical fiber is optically affected by the presence of a measurand medium that can fluoresce, phosphoresce, absorb and/or scatter the probing light. This probing light is guided by the fiber core towards a detector which measures the light intensity and this light intensity is correlated with a measurand.

摘要： Systems and methods of side coupling, side illumination or side injection (as opposed to axial coupling, illumination, or injection) of a waveguide are disclosed. More particularly, it relates to increased coupling, by orders of magnitude, and, consequently, increased transmission, along a waveguide, of any wave by side coupling, side illumination, or side injection.
