1.A theoretical model of dual beam thermal lens effect is derived. The model predicts the intensity distribution and variation in far field of the laser beam in the presence of weakly absorbing medium.
给出了双光束激光热透镜效应的一个理论模型,它预示着激光经微弱吸收介质后的远场光斑强度分布和变化。收藏指正
2.In the dual-galvanometric laser scanning,there was non-linearity mapping relation between the output Cartesian coordinates of object lens scanning plane system and the coordinate of laser scanner. It made the laser scanning geometry to be distorted.
双振镜激光加工中,物镜平场扫描系统中,输出平面笛卡儿坐标系与扫描器球面坐标系之间存在着非线性映射关系,使扫描加工图形产生图形加工畸变。收藏指正
