摘要
研究了激光辐照ＣＣＤ图象传感器局部时，ＣＣＤ工作性能的变化；测量了连续波激光辐照下ＣＣＤ的饱和阈值（分别对１０６０ｎｍ和６３２．８ｎｍ）及脉冲激光辐照下的破坏阈值；分析了造成饱和及破坏的机理；用一维绝热边界条件热模型计算热饱和阈值。
When a CCD detector is locally irradiated with a laser,the working fea-tures of the CCD detector will vary in laser energy density. Extremely,the CCD detec-tor will be damaged. The saturation thresholds of CCD detector,irradiatedwith a CW 1060 nm or 632.8 nm laser, have been measured respectively,The mechanism of satu-ration and damage of CCD detector have been discussed in this paper. By employing one dimension non-conducting boundary condition,the thermal saturation threshold hasbeen calculated.
