中文摘要:
提出应用于激光脉冲高精度时间同步测量的技术方案。利用时间数字转换技术,精确测量激光脉冲相对延时,测量精度可小于10ps(峰谷值)。为满足测量电路对脉冲宽度的要求,设计针对短脉冲激光的电脉冲展宽模块,可以将百皮秒量级的电脉冲展宽至纳秒量级,引入时间抖动的均方根值小于2ps。该测量方案实现了实时高精度时间同步测量,可以作为时间同步反馈补偿的实时监测使用。

英文摘要:
A scheme for high precision time synchronization measurement of laser pulses is presented.The time to digital conversion technology is used to measure the relative time delay of laser pulses accurately,and the measurement accuracy is less than 10ps(the peak-valley value).In order to meet the requirements of the input pulse width of the measuring circuit,an electric pulse broadening module is designed for short laser pulse.An electric pulse signal can be broaden from hundred picoseconds to nanoseconds,with the root mean square of the additional jitter less than 2 ps.This scheme can realize the real-time high precision time synchronization measurement,and can be used for real-time monitoring of a time synchronization feedback compensation system.
