Research output: Contribution to journalArticlepeer-review


This paper is a review and extension of our recent work on three types of singular optical phenomena in statistical optical fields, including phase singularities (optical vortices) in laser speckle fields, polarization singularities in polarization speckle, and coherence vortices in optical coherence functions. For the generation and detection of these unique singular optical phenomena, different optical setups have been introduced. Some geometric structures and statistics associated with singularities are also investigated by experiments.
