Recent Advances in Optical Turbulence

Dear Colleagues,

Refractive index fluctuations can lead to irradiance fluctuations, beam spreading, and a loss of spatial coherence of an optical wave, among other effects, which is known as optical turbulence. Optical turbulence is caused by wind blowing over an aerodynamically rough region of the Earth’s surface in the presence of a temperature gradient. Unfortunately, these detrimental effects have far-reaching consequences for astronomical imaging, free-space optical communications, remote sensing, laser radar, and other applications that require the transmission of optical waves through the atmosphere. Therefore, there is a need to study optical turbulence. We believe that advances in these research fields will push this technology forward.

This Special Issue will cover a range of topics from the field, including, but not limited to, the following:

• Theoretical and experimental results of optical turbulence;
• Novel models of optical turbulence or refractive index structure parameter C_n^2;
• Non-Kolmogorov spectra of optical turbulence;
• Power fluctuations or phase distortions caused by optical turbulence;
• Adaptive optics and other turbulence mitigation techniques;
• Simulation of optical turbulence;
• Optical turbulence’s effect on imaging, free-space optical communications, remote sensing, laser radar, positioning, quantum communications, and other applications;
• Underwater turbulence.

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.
