We describe a nitrogen dye laser—optical multichannel analyzer (OMA) system capable of quickly measuring tissue autofluorescence spectra <i>in vivo</i> at multiple excitation wavelengths. Sample spectra were acquired successfully from patients undergoing gastrointestinal (GI) endoscopic examination.
