Abstract
Methods and apparatus for performing fluorescence and spatially resolved reflectance spectroscopy on a sample. A sample is irradiated with a fluorescence excitation fiber and radiation is collected from the sample with a fluorescence collection fiber and detected to form fluorescence spectra. The sample is also illuminated with a reflectance illumination fiber and reflected light from the sample is collected at a plurality of collection positions and detected to form spatially resolved reflectance spectra. The fibers may form a probe arranged in concentric sections. The spectra are analyzed by pre-processing and reducing the dimensionality of the spectral data.
