In the first part of the workshop Prof. Wolf presented an account of the basic concepts of optical coherence theory. He discussed the distinction between temporal and spatial coherence and concepts such as coherence time, coherence area, coherence volume, and the degeneracy parameter. He then introduced correlation functions that more fully characterize coherence properties of light. He then reviewed important recent developments. In particular he discussed coherent-mode representation of light of any state of coherence, coherence theory of laser modes, radiation from partially coherent sources, coherence properties of Lambertian sources and the effects of source coherence on the spectrum of the emitted light. Coherence effects in scattering of light from random media were also considered. The 2nd part of the workshop was started by Mark Norton of NVEOC who talked about practical applications of coherence. This was followed by a lively discussion regarding the possibility of making coherence filters. Suggestions were also made about future research on such devices and other applications to sensors and discriminators, some of which might use stratified media or holographic filters.
