Optical fields are inherently of a statistical in nature and correlations play an important role in describing the statistical properties of light. The cross-correlations between the fields at two different points, known as coherence function, behaves like a wave. Wave nature and interreference of the coherence function can be utilized to develop various types of non-iterative phase recovery and lensless imaging methods with different waves ranging from optical to matter. Moreover, strong theoretical resources of the coherence optics can be used to steer new trends in the imaging. In this talk, we discuss role of the coherence optics and analogy-inspired approach in the quantitative imaging and phase recovery with random light. We will discuss how and why quantitative imaging with coherence waves(different from optical field) offers new results and insight in the phase recovery, and its possible extension to the polarization domain. Talk also covers design and developments of some unconventional holographic methods such as correlation holography, Stokes holography, Ghost diffraction holography and single pixel Hybrid correlation holography.
