phase microscopy Quantitative phase imagingA comparison of different phase calculation methods that can be used to obtain phase information from the fringes formed by diffraction phase microscopy is presented.As a quantitative phase imaging method, white light diffraction phase microscopy can provide an interferogram non-invasively.Thin film surface interferograms have been retrieved by the white light diffraction phase microscopy which is composed of an optical microscope and a Mach-Zehnder interferometer.There are several techniques for the determination of phase from interferograms.Fourier transform and continuous wavelet transform are the most commonly used methods for phase calculation.Stockwell transform is defined as a phase-corrected version of the continuous wavelet transform method, which is the basis of multi-resolution signal analysis methods.In this study, for the phase calculation of interferograms, Fourier transform, continuous wavelet transforms with Morlet, Paul and zero-order generalized Morse wavelet, and Stockwell transform phase methods have been compared in terms of the precision and the implementation.
