Abstract
The present invention pertains to a method and an apparatus for Raman spectroscopy of human tissue. Human tissue is illuminated with a laser emitting a first wavelength of light. A Raman signal is measured and optical properties are determined at this wavelength such that the measured Raman signal can be corrected based on determined optical properties. Determined optical properties may be the scattering coefficient and absorption coefficient of the tissue. A system for Raman spectroscopy of human tissue includes a frequency sweeping laser light source for illumination, and a filtered detector for collecting the Raman signal.
