This feature issue of Applied Optics contains 31 research papers on photon
correlation and scattering, many of which were presented at an OSA Topical
Meeting that was held 21-23 August 2000 in Whistler, British Columbia, Cana
da. These papers focus on research in dynamic light scattering, surface lig
ht scattering, photon correlation, and laser velocimetry and their applicat
ions to physical, chemical, and biological processes. (C) 2001 Optical Soci
