利用激光诱导荧光技术开发了用于早期鼻咽癌诊断的自体荧光光谱系统 系统由风冷氩离子激光器、自行研制的单色仪和高灵敏度、智能化的信号采集和处理系统组成 文中重点讨论了系统中自体荧光光谱信号的处理技术 ,其中包括荧光光谱信号的分光和检测技术 ,以及用LabVIEW开发的信号处理和控制平台 荧光光谱信号的处理结果表明 :系统不仅实现了荧光光谱信号的同步显示 ,而且极大地提高了信号的信噪比 ,这为系统的临床应用奠定了的基础
The use of laser-induced fluorescence technology developed for the diagnosis of early nasopharyngeal carcinoma autofluorescence spectroscopy system consists of air-cooled argon-ion laser, self-developed monochromator and high sensitivity, intelligent signal acquisition and processing system composed of the article focused on The results show that the system not only achieves the simultaneous display of the fluorescence spectrum signal, but also realizes the signal processing and control of the fluorescence signal, But also greatly improves the signal-to-noise ratio of the signal, which lays the foundation for the clinical application of the system
