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 1):
A fluorescent backscattering system, comprising:\n a housing comprising a housing volume, the housing volume 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; a light source within the housing volume, the light source being capable of generating light comprising at least one wavelength of the first set of wavelengths; a light collector within the housing volume, the light collector comprising a receiving surface, the receiving surface being optically aligned with the second surface; and a sensor for receiving light collected by the light collector, 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.
