| 摘 要： | 自动跟踪式同步机是一种新型的多功能计时、延时仪器。它可以μs精度测量和显示被测时间间隔,并根据测量值自动跟踪被测对象,以±0.2μs的精度输出多路延时讯号,解决各种高速摄影中的同步问题。它具有极强的抗干扰能力,可以在放电电压1mv,放电电流10kA,空间电磁场5kV/m的强电磁干扰的恶劣条件下正常工作。本文详细介绍了自动跟踪式同步机在脉冲X光摄影、可见光高速摄影、动光弹摄影中的应用及其结果。

| Abstract: | The Auto-tracing-Synchronizer is a new type of electronic instrument with multifuctions of time-count and rime-delay. It may count and display a time interval with an accuracy of micro-second. It may trace the measured object automatically and output delayed signals in multi-channels with an accuracy of ±0.2μs so that various synchronization problems in high speed photography can be solved. This instrument has a very strong ability of unti-interference and may work well under serious conditions, such as a strong electro-magnetic interference with a discharge eletric voltage of 1 MV, discharge current of 10 KA and a spatial electro-magnetic field of 5KV/m. The present paper describes exprimental results with this instrument in pulse x-ray photography, high speed photography with visible light and dynamic photoelasticity. |
