A 1st approach to a monitor involved a novel optical scheme involving 2 polymators. The 1st provided excitation at different wavelengths along a flowing sample. The 2nd, operated in reverse, summed selected emission from different portions of the sample. This approach, called "synchronous scan," while successful, was supplanted by a more general approach which utilized the total luminescence of the sample. In this case, the 2nd polychromator was used to disperse emission from the sample at right angles to the excitation dispersion. The total luminescence was then imaged at the exit plane of the 2nd monochromator where a computer-designed mask selected those spectral regions equalizing response of various oil types. Results of tests and progress on a shipboard prototype are discussed.
