Optical Sensors for Industry Applications—2nd Edition

Dear Colleagues,

Optical sensors have been widely applied in many fields of industry, including environmental pollutants, food safety, biomolecules, medical monitoring, industrial process monitoring, process optimization, and condition monitoring, due to their simplicity, low cost, high productivity, less faults, and quick response. For modern industrial systems, reliable sensing technologies for real-time process monitoring, equipment health assessment, and quality control are required. Optical sensors, including fibre-optic sensors, interferometric sensors, fluorescence sensors, absorption sensors, and plasmonic sensors, are able to monitor temperature, strain, pressure, vibration, chemical species, surface conditions, and other critical parameters in industrial systems. Their real-time, remote, and in-line measurements capabilities make optical sensors particularly suitable for smart manufacturing where continuous process monitoring, automated inspection, and data-driven control are increasingly required. In addition, their non-contact and non-invasive characteristics provide important advantages for non-destructive testing (NDT), enabling the detection of defects, structural changes, and material degradation without damaging the inspected components. The basic concepts of these sensors are measuring the changes of optical parameters such as the refractive index, absorbance, reflectance, intensity, lifetime, polarization, etc. The modeling, design, and fabrication of these optical sensors have great potential for various applications in healthcare, environmental protection, food safety, manufacturing process optimization, smart manufacturing, and non-destructive testing in the future.

We invite authors with both engineering and scientific backgrounds, working in any area of optical sensing and applications, to submit their original manuscripts for consideration in this Special Issue. Specific areas of interest include, but are not limited to, the following:

• Optical sensors;
• Non-destructive testing (NDT);

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.
