Paper Abstract

In this paper we show how resolution enhancement in digital holographic microscopy (DHM) and reference-less phase retrieval approach is obtained by using modulated illuminations. The modulated illuminations, including structured illumination and speckle illumination, are generated by a spatial light modulator and used to illuminate the sample. The holograms or diffraction patterns of the object wave under these illuminations are recorded, from which the phase is reconstructed accordingly. The resolution of the reconstructed image has been improved, when the spectrum of object waves along different illuminations are synthesized.
