Physical Review A, vol. 84, 023846, DOI: 10.1103/PhysRevA.84.0238461050-2947http://pra.aps.org/abstract/PRA/v84/i2/e023846http://hdl.handle.net/10204/5861Copyright: 2011 American Physical Society.The authors study numerically the evolution of speckle fields due to the annihilation of optical vortices after the least-squares phase has been removed. A process with multiple steps of least-squares phase removal is carried out to minimize both vortex density and scintillation index. Statistical results show that almost all the optical vortices can be removed from a speckle field, which finally decays into a quasiplane wave after such an iterative process.enOptical vorticesSpeckle evolutionSpeckle evolution with multiple steps of least-squares phase removalArticleChen, M., Dainty, C., & Roux, F.
