【Abstract】 In the paper,the dynamic calibration technology of time interval measuring instrument is studied.The time interval measuring instrument with self-calibration technology can detect the influence of external environmental factors and system aging on the measurement accuracy in real time.When the environmental factors change,the calibration data can be generated in real time for calibration.The related experiments show that the technology can reduce the influence of environmental change and system aging on the measurement system to the order of ten picoseconds,and provide technical support for the design of high-precision time interval measuring instrument.更多还原
