Abstract:
The sensor system monitors solutes in a liquid stream by analyzing the amount of light absorbed in a liquid in a particular wavelength band. The sensor system is arranged for selectability of the type of fiber used for transmission and adjustability of the liquid gap length in the liquid so that individual installations can be arranged with optimum characteristics for sensing particular chemical species in solution by absorption spectroscopy.

Abstract:
A portable system is provided for inspecting presence of a coating on a surface. The portable system includes an optical source and a portable optical probe in optical communication with the optical source. The portable optical probe is arranged to access a surface, emit light onto the accessed surface, and receive light reflected by the accessed surface. A portable color discriminator is in optical communication with the portable optical probe and is arranged to discriminate colors of light received by the portable optical probe. A portable logic controller is arranged to determine presence of a coating on the accessed surface responsive to the discriminated colors of the reflected light. Optional configurations of the portable optical probe, including telescopic, 90 degree, and pivoting sensor tips, allow optical inspection of hard-to-reach surfaces as desired.
