 为有效检测与采集牙齿牙髓荧光信号，将激光诱导荧光技术引入牙齿牙髓活力检测中，设计荧光信号采集与显示电路，采用ADS7804高速转换器与AT89C51单片机为信号采集系统的核心，以TFT-LCD作为显示终端，设计基于单片机的荧光信号采集程序，利用采样数据映射坐标的算法思想处理牙髓荧光信号，通过单片机通讯接口控制显示终端显示荧光信号。系统实现对牙髓荧光信号的采集与显示。
Abstract:
 In order to effectively detect and gather the fluorescence signals of the dental pulp of the tooth，the technology of laser induced fluorescence is used.The gather and display circuit of the fluorescence signals are designed，the ADS7804converters and the AT89C51are used as the core of the system，TFT-LCD is used as the display terminal，a fluorescence signal gathering system basea on the single-chip is designed.With the algorithm idea of sampling data mapping coordi-nate，dental pulp fluorescence signals are processed，display terminal is controlled through the single-chip microcomputer communication interface，in order to finish display of fluorescence signals.The gather and display of fluorescence signals of the dental pulp of the tooth is finished by system
