Optical coherence: description and measurement

Recent work in our group has focused on simple methods for measuring spatial coherence that do not require wavefront division. In particular, we recently proposed an approach where an obstacle is inserted at the test plane, and the difference of irradiance measurements with and without this obstacle gives access to the spatial coherence at all pairs of points whose centroid is the obstacle’s centroid. Our group has also published theoretical work on the propagation of partially coherent fields. (See also section on Wigner functions.)
