TL;DR: In this article, a review about non-destructive testing (NDT) methods for the evaluation of composites is provided, considering the capabilities of most common methods in composite NDT applications such as Visual Testing (VT or VI), Ultrasonic Testing (UT), Thermography, Radiographic Testing (RT), Electromagnetic Testing (ET), Acoustic Emission (AE), and Shearography Testing with respect to advantages and disadvantages of these methods.
Abstract: A review provided about non-destructive testing (NDT) methods for the evaluation of composites. The review considers the capabilities of most common methods in composite NDT applications such as Visual Testing (VT or VI), Ultrasonic Testing (UT), Thermography, Radiographic Testing (RT), Electromagnetic Testing (ET), Acoustic Emission (AE), and Shearography Testing with respect to advantages and disadvantages of these methods. Then, methods categorized based on their intrinsic characteristics and their applications.

TL;DR: Shearography as mentioned in this paper is an interferometric method which employs an image-shearing camera to produce two laterally sheared images in the image plane, which depicts the surface displacement gradients.
Abstract: This paper presents a new optical method referred to as shearography. Shearography is an interferometric method which employs an image-shearing camera. It permits full-field measurement of derivatives of surface displacements. The object under study is illuminated by laser light, and it is imaged by an image-shearing camera. The image-shearing camera produces two laterally sheared images in the image plane. When a photographic film in the image plane is doubly exposed with the object being deformed between the exposures, the processed photograph yields a fringe pattern which depicts the surface displacement gradients. Theory of the method as well as its applications to strain meausrements and nondestructive testing are presented.

TL;DR: In this paper, a fringe system is obtained showing contours of constant slope resolved in the direction of image displacement, which is a comparison with result obtained by holographic interferometry.
Abstract: The surface to be studied is illuminated with laser light and two images are formed, displaced relative to one another in the image. Speckle pattern interferometry is used to measure phase changes between the two images resulting from deformation of the surface. A fringe system is obtained showing contours of constant slope resolved in the direction of image displacement. A comparison is made with result obtained by holographic interferometry.
