用激光散斑剪切干涉法对薄壁压力容器的无损探伤
NONDESTRUCTION TESTER TO THE THIN WALL PRESSURE VESSEL BY LASSER SPECKLE SHEARING INTERFERMOTRY
摘要
Abstract
Laser speckle shearing interfermotry was employed in this paper to test nondestructively a thin wall pressure uessel and clear displacement gradient equal ualue fringe patterns were obtained.The tendency of the fringes coincided with the results by mechnics analysis and the results by double exposed holographic interferometry,which indicate that this method is efffcient for testing the positions of flaws on wall of thin wall pressure vessels.关键词
