Book Description
Humidity measurement in industries is a critical factor, since it may affect the business cost of the product, end product quality, optimal functioning of equipment, and the health and safety of the personnel. Hence, humidity sensing is becoming very important, especially in the control systems for industrial processes. Since humidity is expressed in different ways, it is very difficult to come up with a reliable, consistent, and repeatable humidity measurement approach. In contrast to other sensors employed for measuring other parameters like temperature and pressure, a humidity sensor has to be in contact with the process environment and hence is difficult to implement. This research was initiated at the Diagnostic Instrumentation and Analysis Laboratory (DIAL) for the requirement from the DOE to monitor the moisture in the soil at the nuclear waste storage facility. The idea was to monitor the leakage, if any, in the storage cylinders to avoid any hazard that may come up. The humidity sensor in this case had to be able to transmit the measurement over a distance far away from the actual measurement site. Keeping all these factors in mind, a chemically deposited optical fiber humidity sensor was developed. It was based on the evanescent tail absorption of light passing through an optical fiber due to hygroscopic material deposited on it. The hygroscopic material used was an aqueous solution of Poly-vinyl-acetate (PVA) and Cobalt Chloride (COCl2). The sensor yielded a consistent humidity measurement from 75% to 95%. Based on the above research, research is currently in progress to bring up a commercial prototype of the sensor.

Book Description
This book presents the many different techniques and methods of fabricating materials on the nanometer scale, and, specifically, the utilization of these resources with regard to sensors. The techniques described are studied from an application-oriented perspective, providing the reader with a perspective of the types of nanostructured sensors available that is broader than other books which concentrate on theoretical situations related to specific fabrication techniques.

Book Description
This book focuses on a research field that is rapidly emerging as one of the most promising ones for the global optics and photonics community: the “lab-on-fiber” technology. Inspired by the well-established "lab on-a-chip" concept, this new technology essentially envisages novel and highly functionalized devices completely integrated into a single optical fiber for both communication and sensing applications. Based on the R&D experience of some of the world's leading authorities in the fields of optics, photonics, nanotechnology, and material science, this book provides a broad and accurate description of the main developments and achievements in the lab-on-fiber technology roadmap, also highlighting the new perspectives and challenges to be faced. This book is essential for scientists interested in the cutting-edge fiber optic technology, but also for graduate students.

Book Description
Nanosized sensors enable the study of chemical and biochemical processes at a level and in dimensions that may not have been envisioned some 20 years ago. Fueled by their inherent small size and the unusual optical, magnetic, catalytic, and mechanical properties of nanoparticles, remarkable progress has been made in recent years in the development and utilization of nanosensors and optical nanotechnology will further widen the field. However, the design of new sensors requires new materials, new methods for their characterization, new optical sensing schemes, new approaches for creating nanosized structures, and new techniques for their interrogation in complex environments such as small living cells for studying biological signals or big public spaces for environmental monitoring . Optochemical Nanosensors covers the rapidly growing field of optical chemical nanosensing, a new and exciting area of research and development within the large field of optical chemical sensing and biosensing. Its many applications, including the detection of bioterrorist threats, food security, virology, explosive detection and more, are covered in these self-contained yet interrelated chapters. The book reviews optochemical sensors, starting from the basics in optoelectronicsand concluding with the presentation of diverse nanosensors. The authors offer insight into future trends in this growing field and present applications in the fields of medicine, security, and bioterrorism.

Book Description
Plastic Optical Fiber Sensors cover the fundamentals and applications of a new class of fiber sensors. With contributions from leading academics in the area, this book covers the theory of plastic optical fiber sensors or (POFs), as well as applications in oil, gas, biotechnology, and energy fields. Using multiple examples, the editors showcase the advantageous characteristics of POFs, such as ease of handling, large diameter, inexpensive peripheral components and simple termination tools. By doing so, the editors assert that there has been a proliferation of the use of POFs in new consumer products. The book also highlights uses for building various products, such as a POF sensor for oil trucker valve monitoring, a monitoring system for high voltage substation switch, an oil leaking sensor for offshore platforms and a solar tracker for illumination. Including over 300 black and white images, this book would be highly beneficial for professionals in manufacturing as well as academics in universities, particularly those who use optical fiber sensors on a regular basis.
