| 摘 要： | 激光辐照CCD图像探测器时可造成对探测器的干扰和破坏,为了增强激光对CCD探测器的损伤效果,提出了一种混合频率激光干扰方法,这种方法是将高重频激光和低重频激光耦合,使其同时作用于CCD探测器.基于热传导和热弹性力学的基本关系式建立了混合频率激光辐照CCD探测器遮光铝膜层的热力耦合数学物理模型,对热传导方程和应力平衡方程进行半解析求解,计算得到不同工作模式的激光辐照CCD探测器的遮光铝膜层的瞬态温度场和热应力场,并通过数值仿真定量地比较了不同工作模式激光光源对CCD的损伤效果.结果表明:相对于高重频激光和低重频激光单独作用探测器的情况,混合频率激光将会对CCD产生更加严重的损伤效应.

| Abstract: | CCD arrays can be disturbed or damaged when subjected to laser irradiation,in order to strengthen the damage effect,a kind of mixture frequency laser interference method is put forward,which can couple the high repition frequency laser with the low repition frequency laser to make the both laser irradiate on the CCD in the meantime.The thermal mechanical physical model of CCD light shading Al film irradiated by the mixture frequency laser is set up based on heat conduction and thermal elastic mechanics theo... |
