Abstract
We describe a simple method for measuring the long radius of curvature by using a half-aperture bidirectional shearing interferometer. The m ethod is based on the direct comparison of the fringe widths in the tw o fields. This is very convenient for quantitative interpretation of t he fringes. Detailed analyses for optical arrangements and achievable accuracy are presented. (C) 1996 Society of Photo-Optical Instrumentat ion Engineers.
