Abstract

The use of Fourier fringe analysis as a tool for surface characterization has been well documented. However, there remain several grey areas in the implementation of this technique as a practical tool. Principal among these is the catalog of errors associated with the backbone of the technique--the Fast Fourier Transform. These errors are well known, but their nature and form in this context are not fully understood. This paper gives a detailed review of these problems together with their impact on quantitative measurements and presents possible routes to their elimination and solution.
