| Based on the research project of "Optical-thermal Properties and Optical Biopsy Technique for Nasopharyngeal Carcinoma" of National Natural Science Foundation and others such as Fujian Province Natural Science Foundation, Fujian Province Education Office and so on, technique of spectroscopy system photoelectric signal for diagnosis and localization of nasopharyngeal carcinoma was widely researched in this thesis. Further more, a model device was developed and some relative experiments were made for further developing to get preparative for clinic application in the future.Firstly, a widely study of diagnosis and localization of nasopharyngeal carcinoma national and international was made as many as we can, from which we know how it important to make diagnosis and localization of nasopharyngeal carcinoma and make we sure the possibility by means of non-imaging fluorescence spectrum.Secondly, based on detail analysis and compare of all the correlative fluorescence spectrum measure system, we can firstly make a system diagram and then decide how to make up the total construction and all of its functional sub-module. Then, we have to make a choice how to pick up all the devices we need from what we can get and how to make it work proper according to the system requirement such as precision and so on, which included the system hardware and software.Finally, combined with data acquisition system and PC system, we made some experiments to validate all the parameters of our system to improve or even perfect the performance of the system when all what were told above were done. The preliminary result shows that the fluorescence spectrum measure system for diagnosis and localization of nasopharyngeal carcinoma we designed nearly meets to the requirement of diagnosis medicine of nasopharyngealcarcinoma. We can sure that with the further performance improvement, development of the system is hopeful for the clinic in the future.
