"... an extremely useful reference source for optical sensor designers and for those who apply these types of sensors."—John J. Shea, IEEE Electrical Insulation Magazine, November/December 2015"… a modern, comprehensive overview of optical sensors. … any practitioner wishing to make, improve, or simplify a sensor or its application would do well to consult this text."—Optics & Photonics News, May 2015"… a valuable resource tool for both researchers and industrialists alike seeking to update their knowledge and understanding of the principles behind optical sensing and the diversity of fibre optic sensor systems. It further serves to highlight the potential of optical sensing technology to meet the ever-increasing needs of society for monitoring and control in diverse areas ranging from medical applications to environmental monitoring and industrial process control."—Prof. George Stewart, Centre for Microsystems and Photonics, Department of Electronic and Electrical Engineering, University of Strathclyde, Glasgow, Scotland"… an excellent introduction for young scientists beginning research in the rapidly growing field of modern optics and its applications. … also of great value to current workers in optics as it will become a major reference in the subject."—David A. Jackson, FInstP, FOSA, Emeritus professor of applied optics, School of Physical Sciences, University of Kent, Canterbury, UK"… very useful … It will be of great benefit to students and researchers in this field."—Dr. Conor Hogan, Department of Chemistry, La Trobe University, Melbourne, Australia"This book … can be understood and enjoyed by anyone with a background in physics or engineering, such as an undergraduate student. I would recommend it as a reference for the libraries of many scientists, engineers, and technicians in all fields."—Prof. José Miguel López-Higuera, Head of the Photonic Engineering Group, University of Cantabria, Santander, Spain"... provides a comprehensive and integrated view of optical sensors, addressing the fundamentals, structures, technologies, applications, and future perspectives. ... The 28 authors of these chapters are recognised experts in their areas of research and are major contributors to this field. Therefore, the book offers a broad perspective of the field and identifies trends that could shape the future, such as metamaterials and entangled quantum states of light. This is an ideal resource for practitioners and those seeking optical solutions for their specific needs, as well as for students, researchers, engineers, and technicians in all these fields."—J. Albaigés, CID-CSIC, Barcelona, Spain, from International Journal of Environmental Analytical Chemistry, 2015
