Abstract

The spatial Wigner distribution function of laser light, which contains the laser beam's transverse spatial coherence and propagation property, has been measured by using an interferometric technique. The experimental results show good agreement with theory. Furthermore, a measurement of the Wigner function obtained from a magnified image of a 50 ${\mu}m$ slit gives us a possibility of measuring the spatial coherence on a micrometer scale.
