Objective.The investigations that are developed in this laboratory are divided in two main fields: optical metrology and applications of optical fibers. In the first field, the aim of these works is the development of optical methods, in particular those based in the speckle phenomena, with application in experimental mechanics, nondestructive testing and materials science. The group is also known for its contributions to the development of digital image algorithms, to automate the analysis of the data obtained with the optical techniques previously mentioned and to facilitate their application in the area of industrial inspection. In the optical fiber field, we are devoted to the experimental study of all-fiber lasers, the theoretical and experimental analysis of different photonic mathematical operators performed with optical fibers, especially in the fractional domain, and the characterization of light pulses.
