Digital Polarization holography: Challenges and opportunities

Polarization has a profound impact on image quality, visual perception and completer wave front imaging. For instance, polarization provides a new perspective on seeing an object which is otherwise obscured, low contrast or not measurable by conventional imaging methods. In this paper, we discuss a possible extension of the digital holography (DH) to the polarization domain, and the technique is referred to as digital polarization holography (DPH). Basic principle of DPH is described and some of our recent contributions on quantitative polarization imaging are covered. . We also discuss and highlight potential of combining speckle field illumination with DPH for high-resolution polarization imaging.
