Abstract
This paper presents a method for obtaining the shape of an object using digital shearography. The technique makes use of two types of phase shifting. One provides a nonuniform phase shift which is related to the shape of the object. The other is independent of the shape of the object and utilizes uniform phase shifting. Theory together with experimental verification are demonstrated.
