摘要：

A technique for measuring the radius of curvature of a convex optical surface is described. Its functioning is based on a lateral shearing interferometer and the observation of the collimation of a laser beam. Two interference patterns of straight fringes are obtained, and only when the fringes are parallel is the measurement considered. Since a previous calibration with a laser tracker or similar device is required it is not possible to measure surfaces with radii of curvature longer than ten meters due to dimensions of the laboratory. Details of resolution and measurement uncertainty between calibrated and noncalibrated modes of the instrument are presented.
