Coherence Holography: A Thought on Synthesis and Analysis of Optical Coherence Fields

Coherence plays fundamental role in holography and interferometry, and control of coherence is essential in an illumination system for microscopy and lithography. This talk is intended to give a tutorial introduction to the concept, the principle, and the applications of a new technique of unconventional holography, called coherence holography, which was developed recently for synthesis and analysis of a spatial coherence function [1]. The basic principle of the new technique was inspired by the fact the coherence function 1 1 2 2 ( , ; , ) t t Γ r r and the optical field ( , ) u t r bear a formal analogy in the sense that both obey the same wave equation:
