Spatial intensity correlations of Mathieu speckle fields
Analytical expressions are derived for the spatial coherence function of a speckle field that is generated by the scattering of a Mathieu beam from a random phase mask by following the Fresnel diffraction theory. The general results in the free-space propagation show that the intensity correlation factor is a function of the order of the Mathieu beam, and it evolves spatially as the speckle field propagates. Also, we demonstrate that the intensity correlation factor is non-evolving with the propagation distance in the far-field regime when a lens is placed at the focal distance after the diffuser. The results of this analysis can be used in applications where random fields need to be engineered with structured light beams.
期刊介绍:
The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope.
Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees.
General topics covered include:
• Optical and photonic materials (inc. metamaterials)
• Plasmonics and nanophotonics
• Quantum optics (inc. quantum information)
• Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers)
• Coherence, propagation, polarization and manipulation (classical optics)
• Scattering and holography (diffractive optics)
• Optical fibres and optical communications (inc. integrated optics, amplifiers)
• Vision science and applications
• Medical and biomedical optics
• Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy)
• Imaging and Image processing
