6.1 COHERENCE HOLOGRAPHY

6.1.1 INTRODUCTION

We have discussed so far about several methods using the principle of conventional holography where it records and reconstructs the 3-D image of an object represented by an optical field distribution itself. In 2005, Mitsuo Takeda et.al[46] has proposed and demonstrated a new type of holography, called coherence holography. In coherence holographic technique, the information of the 3-D image of the object is encoded into the spatial coherence function of the reconstructed optical field. Unlike conventional holography, this new type of coherence holography reconstructs the image as the degree of spatial coherence between a pair of points, of which one serves as a reference ...
