Introduction The invention of laser has allowed sources of light with a high degree of coherence, and seeing a new effect with a grainy aspect, which appeared when optically rough surfaces were illuminated with a laser light. After the advent of laser sources, this effect, called speckle, was considered a mere nuisance mainly for holography techniques. However, important research efforts began in the late 60s and early 70s, focusing on the development of new methods for performing high sensitivity measurements on diffusely reflecting surfaces. Nowadays, speckle metrology is a very rich and growing area, widely used in science and industry. This volume contains the papers presented during the Speckle 2010, held in Florianópolis, September 13–15, 2010. This successful international conference started in 2000 in Lausanne, Switzerland, then it was held in Trondheim, Norway in  2003 and, finally, it was organized in Nîmes, France in 2006. This is the first time that the “Speckle” leaves Europe and is held in South America, more precisely in Florianópolis, Brazil. Contributions from 72 papers from all over the world discuss the most recent theories, techniques, and data analysis approaches, as well as the state-of-theart of different applications of the speckle effect in experimental mechanics, material science, optical testing, and developing of sensor systems. Papers presented in this event can be grouped in eleven topics:  Speckle as a tool in security techniques.
