摘要

提出一种基于二次曝光数字全息干涉计量术的轮胎内部气泡缺陷无损检测方法。该方法利用数字全息记录系统记录下轮胎初始状态和受热膨胀变形状态的数字全息图，在计算机中对这些数字全息图分别再现后，将代表轮胎变形状态的再现波前与其初始状态的再现波前进行干涉，获得携带轮胎变化信息的干涉条纹和相位分布，分析存在气泡缺陷区域的轮胎和无缺陷轮胎两种情况下的干涉条纹及其相位分布的特点和区别。研究结果表明：在轮胎内部存在缺陷的位置，其二次曝光数字全息干涉条纹具有与质量正常位置处干涉条纹相对独立的特征，该方法可以检测出轮胎气泡缺陷。

Abstract

A double-exposure digital holography interferometry is proposed and firstly used into the air bubble defect detection of radial tire. A series of digital holograms are recorded during the tire deforming process

the reconstructed images of which are obtained in the computer. After being contrasted the interference fringes between the deformed wave-front and undeformed wave-front of the defect tire and regular tire

the detection rules has been found. The results show that the double-exposure digital holography interference fringes

which lie in the air bubble defect area

have special feature

the proposed method can be used in tire defect diction with high precision.
