Optical Technology for Challenging Conditions：Methods and Applications

Dear Colleagues,

With the ongoing advancements in manufacturing technology and information processing technology, advanced optical imaging/measurement techniques play irreplaceable roles in many fields, such as the biomedical field, neurophotonics, intelligent driving, aerospace exploration, and remote sensing. However, these applications often face complex challenges in terms of application scenarios and environments, such as non-uniform lighting, strong scattering, low light, high noise, and turbulence. Solving the challenges of optical signal attenuation, oscillation, and distortion in complex environments/scenarios is crucial to improving the quality of optical imaging and detection in the aforementioned fields. Consequently, there is a pressing need for the development of cutting-edge optical imaging and detecting systems, coupled with intelligent processing algorithms, to expand the applicability of optical technology in complex environments and bolster its technical resilience.

The purpose of this Special Issue is to provide a platform for researchers to share and discuss their important discoveries, theoretical and experimental advances, technical breakthroughs, methodological innovations, application developments, viewpoints, and perspectives to the community of optical imaging/measurement. All theoretical, numerical, and experimental works related to optical techniques used in complex conditions are accepted. Topics include, but are not limited to, the following:

• Optics in complex media (scattering tissues, turbid water, cloud, fog, etc.);
• Imaging in adverse weather conditions;
• Photometry and lighting technology;
• Optical remote sensing;
• Optical super-resolution, dehazing, denoising/despeckling, and deblurring;
• Target detection in challenging conditions.

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-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.
