Removing Quasi-Periodic Noise in Strain Maps by Filtering in the Fourier Domain

Abstract Quasi-periodic noise due to various reasons often corrupts strainmaps obtained with full-field measuring systems. The aim of this didactic paper is to show how to remove this noise by changing some Fourier coefficients involved in the two-dimensional (2D) Fourier transform of these strain m...
