Abstract

A new lensless microscopy method able to recover the complex wavefront diffracted by a sample from a set of inline recorded holograms is presented. It is based on a modified Gabor-like setup where a condenser lens and a spatial light modulator (SLM) are inserted in a classical Gabor configuration. The condenser lens provides the sample's spectrum at the system Fourier plane while the SLM allows phase shifting modulation of the central spot (DC term) of the sample's spectrum. As consequence, the proposed imaging system recovers the complex amplitude distribution of the diffracted sample wavefront without an additional reference beam. Experimental results validate the proposed method and expand the Gabor method applicability beyond cases of weak diffraction assumption.
