Abstract

This paper describes an installation of the fringe scanning method into a shadow-type Moire Topography. The result is a high-precision three-dimensional measuring system and automatic fringe order measuring system using a liquid crystal plate. A description of this fullyautomatic measuring system, which does not require the user to have knowledge of measuring instruments, is also provided. This system was constructed by achieving the automation of Moire topography, which is regarded as difficult due to problems concerning the linkage of independent processes. The validity of the system is illustrated by experimental results for spheres and for planes with a difference in level.
