History

The activities in this field started in 1999, involving research, development and services in laser-based methods for cleaning, restoration, surface analysis and material characterization applied to cultural-valued pieces, compositional characterization of laser produced plasmas (LIBS) and development of optical/photoacoustic-based methods and instrumentation for quality control processes in the industrial area.

Our group is strongly interdisciplinary and it is the only one of its kind in the country and one of a few in Latin America.

An outlook of the most relevant works of this group involve the development and fabrication of a method and instrument for surface dirt compositional characterization applied to the steel industry (patented and currently working in a steel plant), a method for laser glassware cleaning (patent: Laser cleaning of glassware by opposite incidence), Identification of Mg and Sr traces in Homo Sapiens teeth through LIBS technique, element composition determination of archeological pieces, laser cleaning of antique manuscripts and computer–assisted image processing for surface cleaning quality control.
