Abstract

We present a modified Gabor-like setup able to recover the complex amplitude distribution of the object wavefront from a set of in-line recorded holograms. The proposed configuration is characterized by the insertion of a condenser lens and a spatial light modulator (SLM) into the classical Gabor configuration. The phase-shift is introduced by the SLM that modulates the central spot (DC term) in an intermediate plane, without an additional reference beam. Experimental results validate the proposed method and produce superior results to the Gabor method.
