Abstract:
1. An in-line digital holographic microscopy system for recording phase objects, comprising: a light source configured to emit coherent optical waves; a first beam splitter configured to split the coherent optical waves into object waves and reference waves; an object area configured to accommodate the phase object, wherein the object area is configured to be illuminated by the object waves; a second beam splitter configured to combine the object waves and the reference waves along a common optical pathway to generate interfered optical waves, wherein there is no angle between the object waves and the reference waves downstream of the second beam splitter; and first and second imaging devices configured to record the interfered optical waves at first and second recording planes, the first recording plane positioned at a distance z from an image plane and the second recording plane positioned at a distance z+Δz from the image plane, to generate a first interferogram and a second interferogram.
