Abstract

The paper devises a scheme of Mach-Zehnder Interferometry (MZI) to measure the phase and amplitude of the electric field of image objects signal pulses. By embedding conjugated liquid crystal modulator (LCM) over the MZI setup, through optical spectrometer and charge coupled devices, we obtain the objects interference information being the phase conjugates of the adjusted LCM. On objects phase/amplitude measurement, by utilizing polarization multiplexing scheme, one linear polarization of the reference field is made to vary in quadrature with the other. The latter method of object phase measurement involves no iterative algorithms and is suitable even for complicated phase profiles.
