Abstract:
An apparatus for performing fluorescence and spatially resolved reflectance spectroscopy on a sample, comprising:a light source; a monochromator in optical communication with said light source; a reflectance illumination fiber in optical communication with said light source; a fluorescence excitation fiber in optical communication with said monochromator; an imaging spectrograph; a fluorescence collection fiber in optical communication with said imaging spectrograph; a reflectance collection fiber in optical communication with said imaging spectrograph and in spaced relation with said reflectance illumination fiber; and a detector in optical communication with said imaging spectrograph; wherein said reflectance illumination fiber, said fluorescence excitation fiber, said fluorescence collection fiber, and said reflectance collection fiber define a fiber optic probe, said probe comprising a center section and an outer section, said fluorescence excitation fiber and said fluorescence collection fiber being positioned in said center section, and said reflectance illumination fiber and said reflectance collection fiber being positioned in said outer section.
