Dynamic photoelasticity involves the high-speed recording of rapidly moving fringe patterns in synchronization with loading. Cranz Schardin cameras are routinely utilized in the recording of dynamic photoelastic patterns. There are no moving components in these cameras, making the setup simple and attractive. Amultiple LED camera based on the Cranz Schardin format is presented. Highspeed instant polaroid film is used for recording the photoelastic fringes. Low cost, simplicity in the experimental setup, and rapid repeatability are the advantages of the camera.
动态光弹性涉及与加载同步对快速移动的条纹图案进行高速记录。克兰兹·沙尔丁相机通常用于记录动态光弹性图案。这些相机没有移动部件，使得设置简单且具有吸引力。本文介绍了一种基于克兰兹·沙尔丁格式的多LED相机。高速即时宝丽来胶片用于记录光弹性条纹。该相机具有成本低、实验设置简单和快速可重复性等优点。
