摘　　要：针对生物组织的荧光检测问题,设计了一套微创荧光信号采集系统。该系统由光电信号检测放大系统和数据采集与处理系统两部分构成。光电信号检测放大系统以光电倍增管为核心传感器。数据采集与处理系统采用数据采集卡,以Labview为软件开发平台,实现信号的实时显示和存储。通过在体实验验证和评估,证明了设计的荧光检测系统有着较高的灵敏度和精确度。论文结果对于在体微创荧光检测系统的研究和开发具有重要的价值。For fluorescence detection of biological tissues, we designed an endoscopic fluorescence signal detection system. The system is divided into two parts, including photoelectric detection and amplifying system and data acquisition system. The photoelectric detection part is based on photomultiplier tube. The data acquisition part is based on data acquisition card. Weuse Labview as the software development platform for real-time display and signal storage. The experiments and evaluations proved that the designed fluorescence detection system has a high sensitivity and accuracy. Theresults havesignificance in development of in vivo mini-invasive measurement system.
