【摘要】 本文设计和建立了国内第一台反射型多火花高速摄影系统。与国际上前人的类似工作比较,光路更为合理,像质明显改善。利用此新设备,本文对多种光测方法,进行了初步尝试。文中还分析了半反镜在反射型光路中对偏振度的影响,并给出了补偿方法。更多还原

【Abstract】 This paper reviewed advances of Cranz-Schardin camera,and developed the first sixteen gap reflection mode multiple spark system.Design principles were given in detail. Applying this system,we studied dynamic photoelasticity,high speed photo- graphy and dynamic white-light speckle method.The depolarization effects produced by partial mirror in the system was analyzed and adjusted.The results show that this system is successful and available.更多还原
