Abstract:
1. A system for measurement of a blood analyte comprising: a first light source that emits Raman excitation light; a second light source; a probe having a fiber optic light delivery and collection system for coupling the first light source and the second light source onto a region of material having an endogenous blood analyte, the system collecting Raman light and reflected light returning from the region of material; a detector optically coupled to a proximal end of the probe that detects the collected Raman light and reflected light and generates Raman data and reflected light data; and a processing system connected to the detector such that the processing system receives the Raman data and the reflected light data, the processing system processing the Raman data, reflected light data and a reference Raman spectrum of one or more blood analytes to provide spectral data indicating a concentration of the endogenous blood analyte in the region of material.
