Advanced Fourier Analysis for Understanding Surface Structures and Distortions Using SPIP Software

This article discusses the application of SPIP™ Extended Fourier analysis module for interpreting surface structures and distortions. The SPIP™ software allows users to detect and measure atomic lattice structures and other similar repetitive patterns, enabling advanced filtering to be carried out.

Although Fourier spectrums include critical data about the phenomena of surface structures and distortions, they cannot be easily interpreted.

In contrast, a sub-pixel Fourier algorithm in SPIP™ offers accurate data about selectable Fourier peaks such as wavelengths and the matching frequencies in Hz. This has been shown to be useful for analyzing vibration and noise problems.

The Extended Fourier Analysis Module

The spatial unit cell can be automatically calculated by defining a couple of Fourier peaks related to the reciprocal unit cell (Figures 1 and 2). The spectrum can be edited, Fourier filtering can be performed, and the nature of relationship between Fourier components and image structures can be learned.

The SPIP™ Extended Fourier analysis module serves as a powerful analytical tool; provides a better insight into the association between the Fourier and spatial domain; and functions as an educational toolbox.
