9601778 Hung This Academic Research Infrastructure (ARI) award is made to partially support the development of a new shearography instrument for measuring time dependent deformations. The shearography technique allows full-field and noncontact measurements. The new aspect is to extend the technique to the measurement of time dependent deformations. This new capability will be particularly useful for noncontact and full-field measurements of structural vibrations and for nondestructive testing of large structures such as bridges. An interdisciplinary team of researchers has been formed which includes experts in optics, sensors, mechanics, control and computer and image processing. An interaction with industry is also likely. ***

9601778 Hung该学术研究基础设施（ARI）奖的颁发部分是为了支持一种用于测量随时间变化的变形的新型剪切仪的开发。 剪切散斑技术允许全场和非接触测量。 新的方面是将该技术扩展到时间相关变形的测量。 这种新的能力将是特别有用的非接触和全场测量结构振动和无损检测的大型结构，如桥梁。 一个跨学科的研究小组已经形成，其中包括光学，传感器，机械，控制和计算机和图像处理的专家。 与工业界的互动也是可能的。 ***
