Proceedings of the NATO Advanced Research Workshop, Krakow, Poland, August 26-30, 1996

Since their inception more than 2.5 years ago, photon correlation techniques for the spatial, temporal or spectral analysis of fluctuating light fields have found an ever-widening range of applications. Using detectors which re spond to single quanta of the radiation field, these methods are intrinsically digital in natnre and in many experimental situations offer a unique degree of accuracy and sensitivity, not only for the study of primary light sources themselves, but most particularly in the use of a laser-beam probe to study light scattering from pure fluids, macromolecular suspensions and laminar or turbulent flowing fluids and gases. Following the earliest developments in laser scattering by dilute macro nl01ecular suspensions, in , ... hich particle sizing was the main aim, and the use of photon correlation techniques for laser-Doppler studies of flow and tnrbuence. both of which areas were the subject of NATO ASls in Capri, Italy in 19;:3 and 19;6. significant advances have be('n made in recent years in many other areas. These were reflected in the topics covered in this NATO Advanced Research Workshop, which took place from August 2;th to 30th, 1!)!}6, at the Jagiellonian University, Krakow, Poland. These in cluded ('xperimental techniques. statist.ics and data reduction, colloids and aggregation, polymers, gels, liquid crystals and mixtures, protein solutions, critical pllf'nomena and dense media.


The miniaturisation and performance improvements provided by solid state lasers, fibre optics and avalanche photodiode detectors have given a significant impulse to the use of photon correlation techniques in the study of laser scattering by macromolecular suspensions, liquid surfaces, critical fluids and turbulent liquids. The improvements can be found in experimental technique, colloids and aggregation, polymers, gels, liquid crystals and mixtures, protein solutions and dense media. Powerful new methods of inverse problems are being applied to data analysis. Much progress is being made in the study of dense media using index matching techniques. two colour systems and the theory of photon diffusion. Other notable recent developments are phase transitions in the space shuttle microgravity environment, quantum cryptography and the application of photon correlation at X-ray wavelengths using synchrotron sources. Audience: Postgraduate and industrial researchers interested in particle sizing and particle interactions, the physical chemistry of polymers, proteins, enzymes, viruses and other macromolecules, optical instrumentation, and experiments in space.
