Abstract
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.
