Paper Abstract

In this paper, we demonstrate some direct spatial methods for the optical phase reconstruction: the smoothing method (with numerical averaging window) and the band-pass filtering method (with differential gaussian filter) in the (x,y)-domain for image recorded with a sinusoidal reference, the smoothing method for images recorded with a chirped radial symmetric reference and the band-pass filtering (with differential gaussian filter) in the (x,y)-domain for phase-modulated images recorded with an arbitrary reference. Comparisons between the methods in the (x,y)- and Fourier-domains, as well as the evaluation of the range of phase measurement in these methods are done.
