Paper Abstract

This paper applies the Mach-Zehnder interferometer with an objective lens and an offset lens to magnify the wavefront of an object image, while compensating for the quadratic phase caused by the objective lens and achieving digital holographic microscopy. 1) The single-exposure method and simple arbitrary micro phase step (AMPS) approach are applied to suppress the zero-order and conjugate image interferences caused by holograph reconstruction. Through this process the best conditions for conjugate imaging suppression can be identified via the relative light intensity distribution and noise suppression of the numerically reconstructed object wavefront.
