Book Description
As we enter the nineties, there is worldwide awareness that the future of all mankind is inexorably linked by the world we share, and its response to man's activities. Lasers and the optical sciences have brought powerful tools to measure and understand our environment. LIDAR (laser radar) and laser fluorescence allow us to measure atmospheric and oceanic pollutants, as well as industrial emissions, from many kilometers distance. And a variety of sensitive laser-based spectroscopic techniques permit the accurate analysis of heavy metals and other trace elements in the environment. In September 1989, an international group of scientists me.t in Erice, Sicily, for the 14th Course of the International School of Quant~ Electronics. This Course was devoted to "Optoelectronics for Envi~onmental Science", and was ably directed by Prof. V. S. Letokhov of the USSR Institute of Spectroscopy and Prof. A. M. Scheggi of the C.N.R. Electro magnetic Waves Institute, Florence, Italy. This book gives the proceedings of that conference, which covered not only basic tutorial papers but also reports on the latest research results. The first half of this volume describes the techniques used for direct "In-Situ Measurements" of the environment. In "Techniques and Programs", four chapters and one extended abstract give tutorial discussions of the most important remote sensing techniques: LIDAR, laser fluorescence, and optical fiber sensors, plus a description of the Italian program in this area.

Book Description
Laser spectroscopy is a valuable tool for sensing and chemical analysis. Developments in lasers, detectors and mathematical analytical tools have led to improvements in the sensitivity and selectivity of spectroscopic techniques and extended their fields of application. Laser Spectroscopy for Sensing examines these advances and how laser spectroscopy can be used in a diverse range of industrial, medical, and environmental applications. Part one reviews basic concepts of atomic and molecular processes and presents the fundamentals of laser technology for controlling the spectral and temporal aspects of laser excitation. In addition, it explains the selectivity, sensitivity, and stability of the measurements, the construction of databases, and the automation of data analysis by machine learning. Part two explores laser spectroscopy techniques, including cavity-based absorption spectroscopy and the use of photo-acoustic spectroscopy to acquire absorption spectra of gases and condensed media. These chapters discuss imaging methods using laser-induced fluorescence and phosphorescence spectroscopies before focusing on light detection and ranging, photothermal spectroscopy and terahertz spectroscopy. Part three covers a variety of applications of these techniques, particularly the detection of chemical, biological, and explosive threats, as well as their use in medicine and forensic science. Finally, the book examines spectroscopic analysis of industrial materials and their applications in nuclear research and industry. The text provides readers with a broad overview of the techniques and applications of laser spectroscopy for sensing. It is of great interest to laser scientists and engineers, as well as professionals using lasers for medical applications, environmental applications, military applications, and material processing.
