SELF-REFERENCING FIBER-OPTIC RAMAN PROBE

摘要

In accordance with the present invention, a novel self-referencing fiber optic Raman probe is disclosed. It uses the Raman signal generated by a crystalline optical fiber to normalize the Raman signal produced by the sample in order to compensate for changes in the output power of the excitation laser light source, the coupling efficiencies of the optical fibers connecting the light source to the probe and the probe to the analyzing spectrometer, and the alignment of optical components within the probe.

主权项

1. A self-referencing Raman probe, said self-referencing Raman probe interfacing with a sample and a spectrometer, comprising
a probe body; a probe head comprised of a crystalline optical fiber which serves as an interface between said probe body and said sample; a first port for receiving light from an excitation laser; and a second port for coupling Raman emissions produced by the sample and said crystalline optical fiber into said spectrometer.
