Special Issue Information
Dear Colleagues,
Holography is a frontline technology in optics, photonics, data science, graphic research, and display application. In particular, holographic display technology is believed to be the ultimate 3D display scheme, as it defines the wavefront of light using spatial light modulators (SLMs) (phase shift-type liquid crystal on silicon (LCoS), etc.) by software and algorithm design. The holographic display technology has many powerful advantages, such as per-pixel depth control, being aberration-free, ocular parallax depth cues, and vision correction functionality, and a lot of progress has been made in the field of computer-generated holograms (CGHs). Meanwhile, it can achieve high-resolution images and a large color gamut with advanced display technologies.
The conventional issues with holographic displays, including speckle, image quality, and heavy computational load, have been shown to be resolved using the novel CGH rendering models and higher-performance computing provided by recent graphics processing units (GPUs). However, the quality of SLMs (phase accuracy, etc.) and optical elements in holographic system (waveguide, etc.) also greatly affect the holographic image. The difference between the realistic reconstructed image and simulated image and compact architecture design still remain unsolved problems.
Overall, holography is a rapidly growing research area, with 3D displays in AR/VR or novel applications continuously being developed. The unique benefits of the optical properties of holography, combined with software tools and an algorithm model design used in various photonic systems, will provide a breakthrough for researchers and engineers in many fields of photonics.
Key topics in the field of holography include the following:
- Holographic-based AR/VR technologies;
- A computer-generated hologram (CGH) model for 3D holographic displays;
- Optical system design for holographic near-eye display;
- Spatial light modulator (SLM) issues for holographic image;
- Diffractive optical element (DOE) issues for holography;
- Digital holography and its potential beyond display applications;
- Theoretical and computational studies of holography in photonics;
- High-performance computing (HPC) electronic devices for real-time holograms;
- Artificial intelligence (AI)/machine learning (ML) for holography.

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.
