摘　　要：高精度时间间隔测量技术在军事科技、工程实践、理论研究、激光测距、通信等方面得到了广泛的应用，如何利用飞速发展的FPGA技术结合现有的高精度时间间隔测量技术设计出高性能的测时仪器是目前研究的一个热点．在多次方案论证和实验调试的基础之上创新性开发出了高性能、高精度的时间间隔测量仪，其测量时间间隔最小可达65ps，平均误差小于65ps．High-precision time interval measurement technology has been widely used in military technology,engineering practice,theoretical study,laser ranging,communications and other fields. How to design high-performance time interval measuring apparatus with greatly developed FPGA technology and existing high-precision time interval measurement techniques is a hot issue now. A high-performance time interval measuring apparatus was designed after a number of feasibility studies and experimental testing. The smallest time interval can achieve 65 ps with an error less than 65 ps by mean.
