Advancements in Optical Fiber Sensing

Dear Colleagues,

Optical fiber sensing is a new sensing technology that uses optical waves as the carrier and optical fibers as the medium to sense and transmit external measurement signals. It has attracted tremendous attention over the past few decades due to its small size, light weight, resistance to electromagnetic interference, chemical resistance, and remote sensing ability. Optical fiber sensors can detect changes in temperature, pressure, strain, and other parameters by using the physical properties of light as it travels through an optical fiber. Recently, with the increase in the requirement of high-performance measurement, optical fiber sensing is also constantly evolving. The development of distributed fiber optic sensing technology makes continuous monitoring possible and provides an effective means for the health monitoring of large structures. The construction of fiber optic sensing network, combined with big data analysis, can achieve the real-time monitoring of the complex environment. Advances in micro–nano processing technology include making miniaturized fiber optic sensors, integrating direction, and improving the overall performance of the system and application flexibility. In addition, the introduction of technologies like microwave photonics, artificial intelligence (AI) algorithms, new specialty fibers has further improved the performance of fiber optic sensors, including enhanced stability and resolution and a wider dynamic range. This Special Issue will focus on the advancements in the optical fiber sensor technology and application. The topics of interest include the following:

1. Fiber optic physical, mechanical, electromagnetic, biological, chemical, and medical sensors;
2. Micro- and nano-structured fiber sensors;
3. New optical fiber and its application;
4. Fiber grating sensor;
5. Distributed and multiplexed sensing and sensor networking;
6. Interferometric, polarimetric, and laser-based sensors;
7. New technology and application of optical fiber sensing;
8. Artificial intelligence (AI)-assisted optical fiber sensors.
