Special Issue Information

Dear Colleagues,

We are witnessing an ever-growing landscape of distributed fiber-optic sensors, with innovations in system design, signal demodulation, fiber processing, and functional materials. These include the emerging class of long-range distributed sensors based on the forward transmission of light. Recently, fiber-optic communication–sensing integration has become an important topic, which can pave the way for the cost-effective deployment of distributed sensors across a wide area or long distance.

This Special Issue therefore aims to put together original research and review articles on recent advances, technologies, solutions, applications, and new challenges in the field of distributed sensing systems.

Potential topics include, but are not limited to, the following:

  • Distributed vibration sensors;
  • Distributed acoustic sensors;
  • Distributed temperature sensors;
  • Distributed strain sensors;
  • Distributed pressure sensors;
  • Distributed 3D shape sensors;
  • Distributed chemical sensors;
  • Phase-sensitive optical time-domain reflectometry;
  • Coherent optical frequency-domain reflectometry;
  • Brillouin based optical time-domain reflectometry or analysis;
  • Raman based optical time-domain reflectometry;
  • Fiber grating based quasi-distributed sensing;
  • Forward transmission distributed sensing;
  • Hybrid-system distributed sensing;
  • Machine learning-assisted distributed sensing.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The structural health of fiber-optic communication networks has become increasingly important due to their widespread deployment and reliance in interconnected cities. We demonstrate a smart upgrade of a communication system employing a dual-polarization-state polarization shift keying (2-PolSK) modulation format to enable distributed vibration monitoring. Sensing can be conducted without hardware changes or occupying additional communication bandwidth. Experimental results demonstrate that forward transmission-based distributed vibration sensing can coexist with PolSK data transmission without significant deterioration in performance. This proof-of-concept study achieved a sensitivity of 0.4141 μV/με with a limit of detection (LoD) of 563 pε/Hz1/2@100 Hz. The single-span sensing distance can reach up to 121 km (no optical amplification) with a positioning accuracy as small as 874 m. The transmission rate is 300 Mb/s, the QdB is 16.78 dB, and the corresponding BER is 5.202 × 10−12. For demonstration purposes, the tested vibration frequency range is between 100 and 200 Hz.
