低倍放大高速摄影是对微细目标作动态测定的有效手段。文章将着重介绍如何用接长筒的办法实现低倍放大高速摄影。包括拍摄微细目标的特殊照明方法、放大摄影拍摄参数的选择以及适合于维电器这样的弹性振动的动态特性分析的数据处理技术及其结果。
Low Magnification High-speed photography is an effective measure for making dynamic measurements of fine targets. The article will focus on how to use a long way to achieve low magnification high-speed photography. Including special lighting methods for shooting subtle targets, selection of magnified shooting parameters, and data processing techniques and results of dynamic characteristics analysis suitable for elastic vibrations such as dimensional appliances.
