We have studied the use of image holograms in holographic microscopy. Reducing the degree of spatial coherence in the reconstructing light source reduces the speckle in the reconstructed real image field. A careful choice of recording parameters is necessary to retain the resolution needed to study microscopic objects. Sample photomicrographs of test targets, blood cells, and human hairs are included.
