structure function (SF) is the average height difference squared as a function of separation, which can represent the spatial content of precision surfaces. Linear SF has been applied in astronomy to area data and it captures data of all spatial content. However, it loses the information on anisotropy. The recently introduced two-quadrant area SF characterizes surfaces of arbitrary aperture over any chosen dynamic range while retaining anisotropic information. This paper discusses some computational issues of the SF, analyses the SF for surfaces described by a combination of Zernike polynomial terms and presents an example of its application to a diamond turned surface.

The structure function (SF) represents the average height difference squared as a function of separation and, like power spectral density (PSD), can be used to describe the spatial content of optical surfaces. The linear SF has been applied in astronomy and captures data of all spatial content. However, it loses anisotropic information. The recently introduced two-quadrant area SF (ASF) characterizes surfaces of any arbitrary aperture over all spatial content, while retaining information on anisotropy. This paper relates SF to alternative representations of spatial content, and shows interpretation and combination of the SFs based on multi-instrument data. (c) 2013 CIRP.

The structure function (SF) represents the average height difference squared as a function of separation. The linear SF has been used in astronomy and captures data of all spatial frequencies. However, it does not capture anisotropy on the surface. The one-quadrant area SF has been introduced to represent surface roughness information, but it is inadequate when surfaces are rotationally varying, as is frequently the case for optical surfaces. The recently introduced two-quadrant representation of the area SF can be calculated for any aperture shape, for all spatial content and isotropies. This paper describes the physical interpretation of the two-quadrant area SF and the comparison to area power spectral density (PSD) and area autocorrelation function (ACF) for a range of optical surfaces.
