三脉冲不等强度激光片光源的研制及应用

The application of three unequal energy density Q-modulation laser sheets in detecting small particle field

本文报道了最近研制成功三脉冲不等强度调Ｑ红宝石激光片光源系统。利用小颗粒对片光源９０°方向的散射光对动态颗粒场进行高速摄影，从底片中能够精确直观地判断微小颗粒的瞬时分布、运动方向、速度和加速度情况。

new experimental device of three unequal energy density Q-medula-tion ruby laser sheets source.With the device,the photography of scattering light of small particle field can be taken.The scattering angle is 90 degree.By using the pho-tography,the information of the small particle field can obtained,such as particle dis-tribution,speed,acceleration and their moving directions.
