Preliminary Study of Optoelectric Signal Processing Techniques of Fluorescence Spectroscopy System for Localization of Nasopharyngeal Carcinoma

Drug-fluorescence spectroscopy system for diagnosis and localization of early nasopharyngeal carcinoma has been developed based on the technique of laser-induced fluorescence. The architecture of fluorescence spectroscopy system which is one of the most important part of the nasopharyngeal carcinoma localization system and the processing techniques of its optoelectric signal were discussed in detail, which mainly including the spectrometric and processing technique. The results show that it is not only meets the demand of spectroscopy precision and acquisition density of fluorescence spectroscopy signal but enhances the SNR as well, which provides reliable technical supports for diagnosis and localization of early n.asopharyngeal carcinoma by means of drug-fluorescence spectroscopy.
