摘要
超高速光电分幅相机常用的8 棱锥分光方式在应用于平行光作为背景照明的纹影实验时,原理性的引起了图像的切割。为解决该问题,我们采用多组1:1 分光棱镜代替分光棱锥的空间分光方法来完成光学系统的设计,装调后的相机系统达到了较高的空间分辨率。用研制的超高速光电分幅相机进行了纹影实验,拍摄了脉冲高压作用下的直径Φ30 μm 的钨金属丝爆炸过程,实验结果显示由钨丝爆炸引起的空气冲击波明显,图像均匀完整,没有切割情况出现。研制的光电分幅相机已经在激光与物质相互作用等相关领域的实验中得到了很好的应用。
Abstract
The image dividing method of ultra high speed optic-electronic framing camera using pyramid would induce the un-integrity of the final images when being used in Schlieren experiment. For resolving the problem, we designed the optical system, dividing the image into 8 integrate parts, through the 1:1 dividing prisms. We obtained the high-resolution Schlieren image about Φ30 μm tungsten filament explosive experiment. The ultra high speed optic-electronic framing camera has been used in the field of laser effect.
