本文介绍了一种高速动力学定量研究的时间基准,即研究单次过程的时间基准。文章中首次提出了一种设计单次精密脉冲信号源的新方法,并且运用这种方法研制成功了多通道激光脉冲控制信号源。该仪器能够使关键的几种脉冲时间间隔和各通道之间脉冲延迟时间具有与晶振时钟脉冲同等精度与稳定度,这些时间可以按要求事先予置扣精确测量,也可以重复再现原脉冲系列。仪器中还设计了防止强电磁场干扰的特殊电路。用于控制全息激光系统,一次试验就能获得多幅说明变化的干涉图。
This paper presents a time benchmark for the quantitative study of high-speed dynamics, which is to study the time base of a single process. For the first time, a new method of designing a single precision pulse signal source is proposed in this paper, and a multi-channel laser pulse control signal source is successfully developed by this method. The instrument enables several key pulse time intervals and pulse delay between each channel has the same precision and stability with the crystal clock pulse, these time can be pre-set required deduction accurate measurement, you can also repeat the original pulse series. Instruments also designed to prevent the strong electromagnetic interference of special circuits. Used to control the holographic laser system, multiple experiments can be obtained to explain changes in the interference pattern.
