We propose a simple telescope with three-dimensional image capability for surface profile measurements. Our method based on the algorithm of reflectivity-height transformation is applied to a traditional commercial telescope with a webcam for determining the third dimension of the test object. It is also useful for thickness, deformation, and surface profile measurements.
