Abstract :
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. A way to measure the moments as intensity moments in the output planes of (generally anamorphic but separable) first-order optical systems is presented.
