Digital Holography: Advancements, Applications, and Challenges

Dear Colleagues,

The reconstruction of an image in three dimensions, giving the sensation of relief, is one of the most spectacular and best-known achievements of holography, but there are many other applications in different areas. Holographic interferometry, holographic optical elements, holographic memories, optical information processing, computer-generated holograms, digital holography and security holograms are just a small sample of the numerous scientific and technical applications based on the holographic method. At present, holography is not only limited to the visible spectrum, but holograms can also be made using waves from other regions of the electromagnetic spectrum, thus giving rise to infrared, ultraviolet, microwave or X-ray holography; additionally, new areas in the field, such as acoustic holography, electron holography and neutron holography have also been developed. Finally, holography has found applications in disciplines like engineering and medicine for non-destructive testing and medical imaging.  

This Special Issue is centered on digital holography and its wide range of applications. Topics of interest include, but are not limited to:

• Biomedical imaging;
• 3D metrology;
• Data storage;
• Augmented reality;
• Security and authentication;
• Art and cultural preservation;
• Novel algorithms for holographic image reconstruction;
• Innovations in holographic microscopy for medical diagnosis;
• Advances in holographic data storage technology;
• Miniaturized holographic devices for consumer applications;
• Integration with Artificial Intelligence and machine learning for data analysis.

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. Applied Sciences 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 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.
