Popis:	Two configurations of an automatic bidirectional, fringe‐counting corner‐cube interferometer are compared. They differ only in the method of quadrature phase introduction. The one using polarization coding has good phase stability at optical path differences as large as 955 mm, the one using adjacent beams has such poor phase stability as to render it useless at path differences greater than 700 mm. A useful well‐defined alignment procedure is given for the corner‐cube interferometer.
