The perfect shuffle permutation is an important interconnection scheme in digital optical computing. Various methods suggested for the optical implementation of the perfect shuffle need an anamorphic imaging system. Instead of cylinder lenses Brewster prism telescopes can be used to achieve the desired ratio of 2:1 for horizontal and vertical magnifications. To reduce the rather large distortion of prism telescopes the Brewster concept can be combined with the Amici concept of a straight view dispersion prism.
