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 20):
The method of  claim 11 , wherein the working fluid comprises a lubricating oil, a hydraulic fluid, a brake fluid, a fuel, a grease, a transmission oil, an engine oil, a gear oil, or a combination thereof.
