Abstract
We describe a simple method for measuring the long radius of curvature by using a half-aperture bidirectional shearing interferometer. The method is based on the direct comparison of the fringe widths in the two fields. This is very convenient for quantitative interpretation of the fringes. Detailed analyses for optical arrangements and achievable accuracy are presented.
