Abstract
A new image reconstruction scheme for coherence holography using a modified Sagnac-type radial shearing interferometer with geometric phase shift is proposed and experimentally demonstrated. The reconstruction of off-axis objects placed at different depths makes this proposed technique the most generic one. A reconstructed image, represented by a coherence function, can be visualized with a controllable magnification, which opens up a new possibility for a coherence imaging microscope.
