Laser Spectroscopy for Sensing - Fundamentals, Techniques and Applications

Informationen zum Autor Dr. Baudelet is currently the Senior Research Scientist for the Townes Laser Institute at the University of Central Florida (Orlando, FL). His panel covers the fundamentals of laser-induced plasmas, the application of laser spectroscopies such as LIBS, Fluorescence, Raman, FTIR, as fundamental diagnostics as well as sensing techniques for defense, industrial, environmental, biomedical applications and the study of propagation of ultrashort laser pulses for sensing purposes at distances up to the kilometer range. As Assistant Professor of Chemistry in the National Center for Forensic Science at the University of Central Florida, his research focuses on the application of laser-based spectroscopy for forensic analysis: atomic spectroscopy with laser ablation techniques (LIBS and LA-ICP-MS) as well as molecular with Raman spectroscopy. A large part of his research focuses also on the quantification of interferences in spectroscopic signals. Klappentext Laser spectroscopy has become a diverse field, with applications in numerous areas of physics, chemistry, and biology. Developments in ultrafast laser technology have led to improvements in the sensitivity of laser spectroscopy techniques. Laser spectroscopy can be used to sense solids, liquids and gases for medical diagnostics, environmental monitoring and forensic investigations, and it is critical to the understanding of many industrial and biological processes. Part one covers fundamentals of laser spectroscopy, while part two describes the techniques of laser spectroscopy and part three discusses the applications of laser spectroscopy, such as the detection of chemical, biological and explosive threats. Zusammenfassung Part one covers fundamentals and techniques of laser spectroscopy! while part two describes data analysis and applications of laser spectroscopy such as the sensing of chemical! biological! radiological! nuclear! and explosive (CBRNE) threats.
