Fiber-optic sensors, a class of sensing devices with high sensitivity, compact size, and immune to electromagnetic interference, are widely used in the measurement of various physical, chemical and biomedical parameters, such as temperature, strain, displacement, refractive index, liquid level, torsion, curvature, humidity, magnetic field, viruses, bacteria, etc. As optical fibers have intrinsic sensitivity to temperature and strain, simultaneous measurement of multi-parameter is necessary for practical sensing applications. Innovative sensor architectures are needed to compensate the crosstalk sensitivity, hence to meet sensor versatility requirements. Fiber gratings, cascaded sensing structures, sensitive materials, or functional materials are often adopted in fiber optic sensors to achieve simultaneous multi-parameter measurements. It is noted that tracking the latest multi-parameter measurement techniques and multi-channel signal demodulation techniques can offer the possibility of the practical application and commercialization of fiber optic sensors.
In this Research Topic, a collection of articles is intended to cover recent original research works on simultaneous multi-parameter measurement technologies and multi-channel signal processing methods, simulation, and experimental works on the structural design, sensor fabrication, and sensing applications of multi-parameter measurement fiber devices.
This Research Topic will focus on the following topics, but not limited to:
• Grating-based multi-parameter optical fiber sensors
• Fiber interferometers with intrinsic reference
• Cascaded fiber structures
• Multi-parameter measurement based on functional materials
• Hybrid fiber/waveguide structure
• Lab-on-a-chip technology
• Field trials of multi-parameter fiber sensors
Keywords:
Optical sensing, Simultaneous measurement, Multi-parameter detection, Fiber-optic sensors, Cascaded/hybrid structures
Important Note:
All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
