Y. Surrel, EXTENDED AVERAGING AND DATA WINDOWING TECHNIQUES IN PHASE-STEPPING MEASUREMENTS - AN APPROACH USING THE CHARACTERISTIC POLYNOMIAL THEORY, Optical engineering, 37(8), 1998, pp. 2314-2319
The extended averaging technique and the data windowing technique used
in phase-stepping are investigated using the characteristic polynomia
ls. II is shown that the phase measurement algorithms derived using th
e extended averaging technique are not in general more efficient and m
ay require more samples than those obtained directly from the rules of
the characteristic polynomial theory. (C) 1998 Society of Photo-Optic
