Optical Imaging and Signal Processing for Biomedical Applications

Dear Colleagues,

Optical imaging is a powerful and versatile technology that can be used to visualize biological structures and processes at various scales, which cover molecules, cells, tissues, entire organs, and in vivo body levels. By exploiting interactions between light and tissue, such as absorption, scattering, fluorescence, and reflectance, optical imaging provides non-invasive, high-resolution, and real-time visualization of biological systems. Biomedical signals contain critical diagnostic information buried in noise and artifacts. By extracting meaningful information from complex, noisy physiological data, signal processing provides powerful tools to enhance, analyze, and interpret the complex datasets, enabling breakthroughs in healthcare and research.

Recent advances, including high-resolution optical imaging modalities, artificial intelligence, and computational algorithms, continue to expand the role of optical imaging and signal processing in the observation and analysis of biomedical procedures.

We believe that this collection of articles will be a valuable resource to those who are interested in harnessing advanced optical imaging and signal processing tools for biomedical research. We hope that it will inspire further innovation and collaboration in the field, leading to new perspectives and breakthroughs in both technology improvement and application expansion.

The objectives of this Special Issue are to report on the advances in optical imaging and signal processing for biomedical applications. Topics of interest include, but are not limited to, the following:

• Phase imaging;
• Computational optical imaging;
• Optical tomography reconstruction;
• High-resolution optical imaging;
• Endoscopic optical imaging;
• Digital holography;
• AI-enhanced signal processing;
• Multimodal imaging.

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.
