Abstract
The present disclosure provides methods, systems, and devices for non-invasively measuring a level of an analyte in a user using Stimulated Raman Scattering. A device can include a Raman pump source that emits pump light toward a tissue at a pump wavelength and a Stokes source that emits Stokes light toward the tissue at one or more Stokes wavelengths. The device can further include one or more mirrors and lenses. The device can further include a beam controller that controls the one or more mirrors and the one or more lenses to target the pump light emitted by the Raman pump source and the Stokes light emitted by the Stokes source at an optimal target location. The device can further include a photodetector that measures light that emanates from the tissue. The device can further include a processor that estimates the level of the analyte in the user.
