Abstract

An approach using the fringe projection technique to perform the 3D profile measurement for a plano-convex lens is proposed. A fringe pattern is illuminated onto the lens object, and a CCD camera is employed to record the transmitted fringes on the screen. Fringes on the obtained image are deformed both by the refractive index and the topography of the object, and are analyzable to retrieve the 3D shape.
