A review: Salinity and temperature measurement based on optical fiber sensors

The study of optical fiber salinity and temperature sensors is essential for enhancing precise environmental monitoring and ensuring the sustainability of ecosystems. Sensor performance is closely linked to their structure, which significantly influences sensitivity and stability. Factors such as transmission mode type, sensing material selection, and structural design all affect the sensor's detection sensitivity and stability. Based on sensitivity to salinity and temperature, optical fiber sensors are classified as intrinsic and extrinsic sensors. This review provides a comprehensive analysis of the structural design, operational principles, and performance characteristics of both intrinsic and extrinsic sensors, focusing on the application and potential of various materials and structures in optical fiber sensor design. It explores how emerging materials, including polyimide and hydrogels, can enhance the sensitivity, accuracy, and stability of sensors, and examines the advantages and performance of single-mode and multimode transmission, such as photonic crystal fibers, hollow-core fibers, and microfibers, in specific applications. The review aims to inspire the use of advanced materials and innovative structures in designing new optical fiber sensors, thereby further improving their performance and application prospects.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
