Abstract
A non-contact method and apparatus for inspecting an object via phase analysis. A projector projects an optical pattern onto the surface of an object to be inspected. At least first and second images of the surface on which the optical pattern is projected are then obtained. The phase of the optical pattern at the surface is changed between the first and second image by moving the projector relative to the object.
