Theory and algorithms of an efficient fringe analysis technology for automatic measurement applications
What's it about?
Phase-based measurement systems have applications in physics, engineering, medicine, biometry, and many others. Thus, algorithms for phase demodulation become a staple requirement of considerable importance.
Why is it important?
In this paper, a set of algorithms for phase evaluation, applicable to automatic applications, is presented. This article includes fringe-pattern normalization, Fourier fringe-normalized analysis, generalized phase-shifting, and phase-unwrapping.
