This paper reports results of full field vibration measurements conducted on a laboratory test case, a cantilever beam, submitted to a transient excitation using an impact hammer. The deflectometry technique in the visible and in the infrared spectra are employed to measure the beam’s vibration field using high-speed cameras. The respective performances and implementations of both techniques, as well as potential applications, are discussed.

使用可见光和红外偏转法对悬臂梁在冲击下进行全场振动测量

本文报告了在实验室测试案例中进行的全场振动测量结果，悬臂梁使用冲击锤进行瞬态激励。可见光和红外光谱中的偏转技术用于使用高速相机测量光束的振动场。讨论了这两种技术的各自性能和实现，以及潜在的应用。
