This volume aims is to illustrate the state-of-the-art as well as the newest and latest applications of photonics in safety and security. The contributions from renowned and experienced Italian and international scientists, both from the academic and industrial community, present a multidisciplinary and comprehensive overview of this popular topic. The volume is self-contained and offers a broad survey of the various emerging technologies, as well as their applications in the real world. It spans from applications in cultural heritage, to environment, space, monitoring of coasts, quantum cryptography, food industry, medicine and forensic investigations. Photonics for Safety and Security provides an essential source of reference for a very wide readership, including physicists, chemists, engineers, academics and students who wish to have a complete review of the subject. The topics are carefully defined and widely illustrated so as to capture the attention of neophytes who need to go further into the topic and explore the research literature.

This invaluable book offers a comprehensive overview of the technologies and applications of optoelectronic sensors. Based on the R&D experience of more than 70 engineers and scientists, highly representative of the Italian academic and industrial community in this area, this book provides a broad and accurate description of the state-of-the-art optoelectronic technologies for sensing. The most innovative approaches, such as the use of photonic crystals, squeezed states of light and microresonators for sensing, are considered. Application areas range from environment to medicine and healthcare, from aeronautics, space, and defence to food and agriculture. Written in a self-contained manner, this volume presents both the sensing methodologies and the fundamental of the various technologies, as well as their applications in the real world.
