Paper Abstract

Recently, extended studies are provided in order to find a robust, accurate measurement method with adjustable sensitivity for determining corneal topography or for the best fitting of contact lenses. A promising method can be moire deflectometry (Talbot interferometry) which is the incoherent analogy to sharing interferometry. Here, an experimental setup for measurement of the topography of the cornea is presented. The possible application of Twyman-Green interferometry for measurement of contact lenses is discussed. The evaluation methods for retrieving the data from the interferograms is discussed.
