An imaging system includes a first light source configured to provide a first light to an object, a second light source configured to provide a second light to said object, a color camera configured to capture an image of the object, a first mirror disposed between the first light source and said object, a second mirror disposed between the second light source and said object, a beam splitter disposed between the color camera and said object, a first filter for the first light source, a second filter for the second light source, and a processor configured to determine at least one of a shape, a deformation, and a strain measurement of said object from the image.

Embodiments of a shearography system may include light sources configured to produce beams of light to illuminate a test area. Each of the beams of light may include a different wavelength. A camera may be configured to obtain intensity information corresponding to reflections of the lights off of the test area. An optical shearing device may be disposed in an optical path between the light sources and the camera and the optical shearing device may be configured to provide a shearing angle.

Spatial phase-shift shearography system for non-destructive testing and strain measurement

A method for detecting the integrity of a bond of a multi-piece work piece includes capturing a first image of the work piece, stressing the work piece, capturing a stressed image of the work piece, and comparing the first image of the work piece with the stressed image of the work piece to determine the integrity of the bond.
