About this Research Topic
Optical sensors are electromagnetically passive, intrinsically safe, lightweight, robust, and easy for remote implementation, multiplexity, or distributed sensing. In recent years, many excellent optical sensors are continuously proposed in conjunction with physical sensing systems and demonstrated not only for measurement of various physical parameters such as strain, temperature, flow rate, pressure, and magnetic field but also for new sensing applications such as structural health monitoring and production process control in special environments. Moreover, the recent remarkable progress in advanced optical technologies, i.e., in-fiber interference, optical resonator, and plasmon, makes it possible to generate, propagate, engineer, convert or detect light in a precise and repeatable manner, which intensively accelerates the development of optical sensors and sheds new light on intelligent and high-performance physical sensors.
This Research Topic aims to highlight the latest progress and trends in advanced optical technologies for physical sensor applications. The topics include the fiber-optic and photonic sensing technologies by adopting new concepts, new materials, new structures, and new principles; the site trials of physical sensors and new insights into advanced optical technologies for manufacturing physical sensors; and the processing approaches of optical sensors ranging from micro-probes to large devices for practical applications. It is anticipated that the readers who are interested in this field will not only see the positive effects of these advanced optical technologies in physical sensor development but also broaden their thoughts and dope out new solutions to surpass the current state-of-the-art. This in turn will pave the way for optical physical sensors to practical applications. It will therefore be no surprise if some of the ideas presented in this Research Topic to be viable in the long term and become the base of innovative commercial products.
This Research Topic calls for manuscripts that devote to theoretical analysis, model simulation, experimental studies as well as practical applications of physical sensors (temperature, humidity, strain, flow rate, pressure, magnetic field, etc.) based on advanced optical technologies.
