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.
