Polarization Spectrum Video Imag-ing Detection of Laser Irradiated Composite Epoxy Resin Damage

本文采用偏振光谱视频成像的在线检测识别方法,结合偏振双向反射分布函数的探测原理和数学模型,研究偏振光谱成像主动探测复合环氧树脂在激光辐照下的损伤演化过程。依据斯托克斯(Stokes)矢量分析法,分析复合环氧树脂表面随激光脉冲数目和脉冲能量增加所引起的损伤变化规律。

In this paper, the online detectionand identification method of polarization spectrum video imaging is used,combined with the detection principle and mathematical model of polarizationbidirectional reflection distribution function, to study the damage evolutionprocess of composite epoxy resin under laserirradiation. According to Stokes vector analysis method, the damage changelaw of composite epoxy resin surface with the increase of laser pulse numberand pulse energy is analyzed.
