Special Issue Information
Dear Colleagues,
Distributed optical fiber sensors (DOFSs) have attracted tremendous attention since the 1980s after low-loss optical fiber was successfully manufactured. Via the Rayleigh/Raman/Brillouin backscattered light or forward transmission light in the optical fiber, DOFS is able to perceive external physical perturbations along the whole fiber such as temperature, strain, acoustic vibration, and pressure. Benefiting from the state-of-the-art optoelectronic devices and advanced modulation methods, DOFS has demonstrated significant advantages in sensing range, spatial resolution, sensing resolution, etc. Furthermore, the intrinsic distribution sensing capability and passive feature endow the DOFS with great resilience in harsh environments where conventional electronic sensors struggle to survive, and even the electronic counterparts are absent.
Nowadays, DOFS is still the subject of highly active research and has been widely used in numerous fields. Researchers worldwide have proposed various schemes to continuously advance the performance of DOFS. Meanwhile, data-driven machine learning and AI techniques have become a trend to enhance the perception applicability of DOFS. Moreover, new interdisciplinary investigation is emerging as DOFS is regarded as the routine tool in many scientific research and industry areas such as geophysics, oil and gas industry, and structure health monitoring.
We are pleased to invite you to share your latest research progress in this Special Issue organized by Photonics. We hope all of these efforts can accelerate the development and application of the DOFS.
This Special Issue aims to publish high-quality papers focusing on original scientific research as well as valuable applications of DOFS.

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. Photonics is an international peer-reviewed open access monthly 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 2400 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.
