摘要: 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.Abstract: new experimental device of three unequal energy density Q-medulation 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 photography,the information of the small particle field can obtained,such as particle distribution,speed,acceleration and their moving directions.
