摘要
采用超短激光脉冲对一台四通道超高速分幅相机曝光过程进行时间扫描,测定超高速分幅相机时间响应特性.通过对四个通道的同时测定,给出最短曝光时间下相机所有通道的时间响应特性曲线.由此曲线得到相机各通道的实际曝光时间、开/关门时间、曝光过程中的响应变化以及四个通道不同的响应特性等诸多信息.通过对相机时间响应特性的测定,考核相机的实际工作性能与工作状态,并为实验数据解读提供参考.超短激光脉冲扫描法可以作为高速摄影类设备时间响应特性测定的标准方法.
Based on the scanning method with ultra-short laser pulse,the measurement of time response characteristic was implemented on a Ultra High Speed Framing Camera(UHSFC)which has four channels.All of the four channels'curves of time response were carried out simultaneously.Actual exposure time,opening and shutting time,modulation of response and so on were revealed in these curves.The actual performance and state of the UHSFC can be examined with the help of these information.The analysis of experimental data can also be profited from the mensuration.
