摘　　要：研制的皮秒时间相关单光子计数(TCSPC)光谱仪采用了具有分光时间弥散动态和静态补偿特性的光栅分光系统,利用多道谱分析仪开设时间窗口,测量时间分辨光谱。给出了光谱仪的原理和总体方案,介绍了系统的集成和工作流程。通过各种标准样品的试验数据分析和对比,得出系统具有最高的灵敏度—单光子计数,时间分辨率达到8.8ps。A picosecond time-correlated single photon counting (TTCSPC) spectrometer was developed using a peculiar splitter technique. Therefore the time spread can be dynamically and statically compensated. The multichannel analyzer was used to measure the time-resolved spectrum by opening the time windows. The theory and design of the spectrometer were presented in detail, and the process of operation was introduced with the integration of the system. Many standard samples have been measured and the data have been analyzed and contrasted. Experimental results show that the spectrometer's sensitivity is single photon counting and time resolution is 8.8 ps.
