동경방향 스펙클 전단 간섭계를 이용한 대칭형 물체의 진동 모드 특성에 관한 연구
A study on characteristics of mode shapes of symmetrical objects using radial Electronic Shearograhpy
초록
In this paper, radial sheared eletronic shearopgraphy was studied in order to measure vibration characteristics of circular or radial symmetric objects. We calculated amplitude of vibration by using eletro-optic holography theory, and utilized a porror prism for optical arrangement of sheared two images in this experiment. In this case, the data measured by shearing interferometer give us a distribution of the gradient of vibration amplitude. This developed system is applied to symmetical objects such as fans of airconditioner and circular plates to test vibration characteristics.
