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。 This paper designs and establishes the first multi-spark high-speed photography system in China. Compared with the similar work done by the foreigners in the world, the light path is more reasonable and the image quality is obviously improved. With this new device, this article has made a preliminary attempt to a variety of photometric methods. The paper also analyzes the influence of the half-mirror on the polarization degree in the reflective optical path, and gives the compensation method.
