Paper Abstract

A new coherent method for measuring the topography of curved surfaces is presented. The sensitivity of the method is adjustable and thus the proposed technique closes the gap between the white light and interferometric measuring methods. The method yields the deflection angles in x- and y-direction obtained from deflectograms. These angles are used for calculating the topography of the object under study. A brief description of the theory is given. The first experimental results for a simulated corneal surface are demonstrated. This technique can be suitable for measurement of contact lenses or corneal surface.
