摘要
高速摄影技术是研究激光与物质相互作用的一种重要手段,由于曝光容许度限制难以完整记录整个作用过程。从光谱角度对相机的感光特性、高温物体的辐射特性和照明条件分析,提出采用截止滤光片降低高温物体亮度的方法,并计算得到截止滤光片的参数。实验结果表明目标的亮度动态范围得到有效控制,显著提高了拍摄质量。
High-speed photography is an important method in researches of laser interacuon wtm matter. It is hard to record the entire process because of the short exposure tolerance. Based on the analyses of relative sensitivity, radiation distribution of high temperature object and illumination, we present a new method to lower the exposure by low-pass optical filter. The filter＇s parameter was calculated by numerical method. The experiment showed that the wide temperature dynamic range was compressed effectively.
