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 11):
A method for characterizing a working fluid using fluorescent backscattering, comprising:\n passing a working fluid through a volume of a working fluid environment, the working fluid optionally comprising 1 wppm to 1000 wppm of a fluorescent marker, the volume of the working fluid environment comprising a first surface that is at least partially transparent to a first set of wavelengths and a second surface that is at least partially transparent to a second set of wavelengths, at least one of the working fluid and the fluorescent marker comprising a fluorescent transition capable of being excited by one or more wavelengths of the first set of wavelengths and generating fluorescent light comprising at least one wavelength of the second set of wavelengths; generating light comprising at least one wavelength of the one or more wavelengths, at least a portion of the generated light being incident on the first surface; and receiving, through the second surface, fluorescent light generated by the fluorescent marker, wherein the first surface and the second surface are the same, or wherein the first surface and the second surface are separated by 1.0 cm or less.
