Abstract

A technique has been developed for measuring the shape of aspherical lenses. The method uses the double exposure holographic technique. The observed fringe pattern is evaluated by computer for characterising the shape of the lens to be tested. The sensitivity of the measurement can be tuned by controlling the technique for producing fringe pattern.
