On the Wigner distribution moments of rotationally symmetric, partially coherent light
نویسندگان
چکیده
The Wigner distribution of rotationally symmetric partially coherent light is considered and the constraints for its moments are derived. While all odd– order moments vanish, these constraints lead to a drastic reduction in the number of parameters that we need to describe all even–order moments: whereas in general we have (N + 1)(N + 2)(N + 3)/6 different moments of order N , this number reduces to (1 + N/2) in the case of rotational symmetry. A way to measure the moments as intensity moments in the output planes of anamorphic first–order optical systems is presented. Keywords—Wigner distribution, partial coherent light, phase space signal description, optical beam characterization, rotational symmetry, second– and higher–order moments

On rotationally symmetric partially coherent light and the moments of its Wigner distribution
The Wigner distribution of rotationally symmetric partially coherent light is considered and the constraints for its moments are derived. While all odd-order moments vanish, these constraints lead to a drastic reduction in the number of parameters that we need to describe all evenorder moments.

متن کاملReduced forms of the Wigner distribution function for the numerical analysis of rotationally symmetric synchrotron radiation.
In an effort to provide a computationally convenient approach to the characterization of partially coherent synchrotron radiation in phase space, a thorough discussion of the minimum dimensionality of the Wigner distribution function for rotationally symmetric sources of arbitrary degrees of coherence is presented. It is found that perfectly coherent, perfectly incoherent and partially coherent...
متن کاملPhase-space tomography with a programmable Radon-Wigner display.
We show the adaptation of a multifunctional optical system consisting of two spatial light modulators for the optimal measurement of the Radon-Wigner transform of one-dimensional signals. The proposed Radon-Wigner display allows reconstructing the Wigner distribution and the phase or the mutual intensity of fully or partially coherent fields, respectively. It is also suitable for the analysis o...
متن کاملWigner Distribution Moments Measured as Intensity Moments in Separable First-Order Optical Systems
After the introduction of the Wigner distribution (WD) [1] for the description of coherent and partially coherent optical fields [2], it became an important tool for optical signal/image analysis and beam characterization [3, 4, 5]. The WD completely describes the complex amplitude of a coherent optical field (up to a constant phase factor) or the mutual coherence function of a partially cohere...
