Paper Abstract

We describe a phase-stepping and subsequent phase-unwrapping technique with tricolor images for the analysis of isochromatics and isoclinics using arbitrary retarded retarders. A retarder used in the proposed method is not necessarily a quarter-wave plate specified for the wavelength of the light used. Not only the isochromatic and isoclinic parameters but also the retardation of the input and output retarders are determined simultaneously by the proposed phase-stepping method. Thus, any wavelength of visible light can be used in a single polariscope requiring matching the wavelength of the quarter-wave plate. Utilizing the characteristics of the proposed method, phase-unwrapping and ambiguity correction can be performed with phase maps obtained for three different wavelengths.
