Abstract

The key to a successful fiber optic sensor design is to maximize the interaction between the optical radiation carried in the waveguide and the chemical species. Of the various designs that have been discussed evanescent and end fire have been the most widely used in chemical sensing. These approaches are best with fluorescent chemistry systems. Absorbance based optical fiber sensing systems offer the advantages of being adaptable to a wider variety of sensing chemistries. Historically single fiber systems for absorbance sensing have not been feasible without having an external mirror attached to the fiber end. The external attachment of the sensing chamber and mirror increase the size fragility and cost of the sensor. We have developed a novel single fiber sensor that shapes the end of the fiber into an optical element and places the chemistry within the fiber itself.
