Paper Abstract

Industrial development has led to the release of numerous hazardous materials into the environment, posing a potential threat to surrounding waters. Environmental analysis of sites contaminated by several chemicals calls for continuous monitoring of multiple analytes. Monitoring can be achieved by using imaging bundles for the fabrication of sensors. Imaging bundles are formed by melting and drawing together several thousand individual optical fibers. The fibers are drawn coherently so that the position of an individual fiber of the bundle at one end (distal) corresponds to the identical position at the other end (proximal). By coupling imaging fibers to a charge coupled device (CCD), one has the ability to spatially discriminate the distal end of the fiber.
