Special Issue Information
Dear Colleagues,
Distributed optical fiber sensing (DOFS) technology has attracted much attention for static and dynamic measurements. The optical mechanisms include Brillouin, Rayleigh and Raman scattering, as well as some interferometric approaches. Over the last decade, researchers have made great efforts to develop high-performance distributed fiber sensors by improving the spatial resolution, dynamic response, sensing distance, measurement accuracy, frequency response range, and so on. Performance-enhancing methods have included the use of optical frequency combs, pulse coding, smart optical amplification schemes, signal processing techniques, artificial intelligence, and many others. Meanwhile, DOFS technology has been adopted in a wide range of application fields, such as structural health monitoring, intrusion detection, pipeline monitoring, fire detection, traffic tracking, geological exploration, and so on.
The objective of this Special Issue is to provide an update on the current state of the art of distributed optical fiber sensing, including fundamental research and novel field applications.

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.
