Abstract:
Systems and methods are provided for in-situ characterization of a working fluid based on fluorescent backscattering. Instead of attempting to transmit light through the working fluid, backscattered fluorescent light generated by the working fluid and/or by a fluorescent marker in the working fluid can then be detected. Thus, fluorescence can be induced in or near a surface layer of the fluid relative to the housing containing a light source, and the resulting fluorescence can be detected by a detector located in the same housing or an adjacent housing. By avoiding the need to transmit light through the liquid, difficulties with absorption and/or scattering due to particles, soot, or other debris in the working fluid can be reduced or minimized. This can allow detection of the fluorescence to be maintained as a working fluid ages.

Claim (Index 18):
The method of  claim 17 , wherein the fiber optic collector passes the received fluorescent light to a sensor, the sensor generating one or more intensity values based on the received fluorescent light, the method further comprising characterizing the received fluorescent light by i) comparing the generated one or more intensity values with one or more reference values, ii) calculating a characteristic value based on the generated one or more intensity values and comparing the characteristic value with a reference value, or iii) a combination of i) and ii).
