Abstract

随着短脉冲激光技术的快速发展，CCD图像传感器受到的潜在威胁呈现区别于传统连续/长脉冲激光的新特征。为了探究不同波长短脉冲激光致CCD图像传感器干扰损伤的影响机制和作用原理，选用波长为1064 nm、532 nm，脉宽为30 ps，重复频率为1 Hz的皮秒激光对可见光CCD进行干扰损伤实验研究，通过光学显微镜、图像传感器自身成像观察CCD干扰损伤不同阶段辐照效能，分析了短脉冲激光对CCD干扰损伤的机理，对比了两种波长激光辐照CCD不同阶段的成像图像、微观形貌以及阈值。结果表明，对可见光CCD，波长532 nm激光比波长1064 nm微透镜层贯穿能力更强，波长532 nm激光比波长1064 nm激光干扰阈值低1−2个数量级，点损和线损阈值低2个数量级。
