Abstract

This paper proposes a method to obtain the shape of large plane surfaces by connecting measured phase distributions by a small aperture interferometer. To correct tilt and vertical displacement of individual phase distributions, measurements are made so that areas of the measurement have common area with the adjacent areas and then these are connected by minimizing squared difference in the common areas. An experimental result of connection is also shown.
