Optical fiber sensors track delves into a diverse range of topics, including the development of novel optical fiber sensor technologies, the design of sensing systems, the exploration of cutting-edge optical materials and the application of such systems in real-world scenarios spanning from structural health monitoring and environmental sensing to healthcare and industrial automation. The focus of the topic will be on point (interferometric, polarimetric, refractometric and grating based), quais-distributed and distributed sensors. Examples include, but are not restricted to, gyro, current, magnetic field, radiation, bio and chemical, strain, temperature, pressure, vibrations, hydrophone arrays, shape sensing, DAS, OTDR and OFDR.
Laser Based Sensors
Laser Based Sensors are based upon direct and indirect detection of laser light interacting with a target object, which inherently allow for non-invasive measurements with high precision and high accuracy as well as fast response. Thus, demands and challenges for laser-based sensors continue to grow in both science and technology. The topics of Laser Based Sensors include laser ellipsometry, laser speckle imaging, laser spectroscopy, laser Doppler vibrometry, laser interferometry, laser light detection and ranging and laser-based quantum-enhanced sensing.
Optical Biological and Chemical Sensors
Technologies such as fluorescence, Raman and infrared spectroscopy, fiber optics, silicon photonics, nanophotonics and plasmonics have all found recent application in chemical and biological sensing. These sensors utilize similar scientific principles to tackle a wide variety of detection challenges from multiple disciplines. Applications for these sensors addressing the critical needs in health, environment, food, forensics, safety and security are all a focus of this topic.
Innovations in source and detector technologies, tailored electromagnetic materials and computational intelligence are making the terahertz spectral region (0.1 - 30 THz) much more accessible for innovative sensing concepts. This topic features contributions in all these areas, with an emphasis on exploring how the terahertz region provides unique capabilities to detect and recognize unique signatures.
