Abstract

The wave aberrations determine the quality of the focal spot and more general the imaging quality of the lens under test. Here we propose the measurement of the wave aberrations with the help of a Twyman-Green interferometer adapted to the special requirements for testing holographic optical lens elements. The evaluation of the interferograms is done with the phase-shifting technique. The resulting wave aberrations are expanded as Zernike polynomials. In addition to this evaluation the point spread function and the modulation transfer function are calculated from the wave aberrations. The setup the evaluation method and some exemplary results of a tested holographic optical element are presented.
