Abstract

Most optical workshops and many research workers have the use of simple double-pass interferometers that use laser sources. Many such workers are familiar with the different patterns formed by the interferograms resulting from aberrated optical systems, but few workers seem to appreciate the effects of such wavefront deviations on the final image produced by those systems. This paper uses a novel technique to plot the fringe patterns produced by each of the Sixth Order Aberrations, and then goes on to plot pseudo-isometric views of the resultant Point Spread Functions. A comparison is made with the corresponding geometrically-generated Spot Diagrams, to demonstrate the superiority of the diffraction-based calculation over the old-fashioned geometrical method.
