A measurement system of exposure time is introduced. The jitter time MCP gating pulse is rapidly measured using an array of fiber bundle(AFB) and pulse-dilation framing camera. The research results show that the AFB is early or delay synchronized with MCP gating pulse by the pulse jitter result in the variation of position of maximum intensity of the dramatic imaging of the AFB. According to the variation of position, while the MCP gating pulse has a width of 200 ps and amplitude of −1.75 kV, the left and right jitter time of gating pulse are 61 ps and 73 ps, respectively. The measurement method provide a conveniently diagnosis to estimate jitter time of MCP gating pulse.

介绍了曝光时间的测量系统。抖动时间MCP门控脉冲使用光纤束（AFB）阵列和脉冲膨胀成帧相机快速测量。研究结果表明，由于脉冲抖动，AFB与MCP门控脉冲提前或延迟同步，导致AFB剧烈成像的最大强度位置发生变化。根据位置的变化，MCP门控脉冲的宽度为200 ps，幅度为-1.75 kV，而门控脉冲的左右抖动时间分别为61 ps和73 ps。该测量方法为估计MCP门控脉冲的抖动时间提供了方便的诊断方法。
