Image plane holograms for holographic microscopy.
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.
