Abstract
Recent developments in digital processing have renewed interest in E.S.P.I., whereby direct contouring is possible with fringes of interferometric quality. It is now possible to locate points on the object accurately in association with E.S.P.I. analysis, although a trade-off between point resolution and fringe visibility seems likely. Nevertheless the time is close for the development of a complete optical inspection system.
