摘　　要：为了有效对抗时间延迟积分电荷耦合器件成像设备的干扰,采用脉宽为10ns、波长为1.06μm的脉冲激光对其进行了干扰实验。分析了干扰现象与机理,采用数字图像处理方法测量了饱和阈值。结果表明,当激光能量密度为1.33m J/cm2时,时间延迟积分CCD达到饱和;提高激光重复频率可以取得更有效的干扰效果。In order to confront time delay integration charge coupled device（ TDI-CCD） imaging equipment efficiently,theoretical analysis and experiments about pulse laser interference on TDI-CCD with pulse width of 10 ns and wavelength of 1. 06μm were conducted. Interference phenomena and mechanisms were analyzed. Saturation threshold was measured by digital image processing method. The results show that saturation threshold is 1. 3m J / cm^2. Interference will be more effective if pulse repetition frequency is higher.
