We present an asynchronous phase-shifting demodulation approach based on the principal component analysis method that is robust to typical problems as turbulence, vibrations, and temporal instabilities of optical setup. The brings together a two-step share their benefits while reducing intrinsic limitations. Thus, proposed two-fold process. First, modulating phase estimated from approach. Secon...

This article presents a discussion of principal components analysis descriptive sensory data. Focus is on standardization, many correlated variables, validation, and the use data in preference mapping. Different ways performing are presented discussed with focus how to obtain informative reliable results. The results will be commented light experience. All methods illustrated by calculations ba...
