Abstract
An optical configuration for a digital holographic microscope and a method for digital holographic microscopy are presented. In one embodiment, digital off-axis holograms are obtained using a cube beam splitter () to both split and combine a diverging spherical wavefront emerging from a microscope objective (). When a plane numerical reference wavefront is used for the reconstruction of the recorded digital hologram, the phase curvature introduced by the microscope objective () together with the illuminating wave to the object wave can be physically compensated.
