Abstract
The potential of fluorescence spectroscopy for diagnosis of epithelial neoplasia has recently been demonstrated.1 Tissue fluorescence spectra result from a weighted average of contributions from various layers; depth of penetration is governed by tissue optics, ranging to hundreds of microns. The optical sectioning property of the confocal fluorescence microscope can. be used to collect fluorescence from a particular layer with depth resolution of less than a micron.2 We have designed and constructed a confocal fiber optic spectrometer (CFOS) that combines both these properties. Data obtained from dilute and scattering samples are presented. Implications for enhancing tissue diagnosis and studying light propagation are discussed.
