Dr. George Nehmetallah, associate professor in the Department of Electrical and Computer Science, will serve as a Program Chair Committee Member for the international “Optica Digital Holography and Three Dimensional Imaging Topical Meeting” conference this summer in Capaccio Paestum, Italy. This conference, hosted by Optica (Optical Society of America), is an interdisciplinary meeting focused on topics related to science, technology, applications of digital holography, and three-dimensional imaging. Experts and companies from around the globe travel to the conference each year to present their research or imaging products and discuss their findings.
This year, the conference consists of 135 oral presentations, 40 invited talks, keynote speakers, and tutorials, and 40 posters that address several recurring and novel topics. Some of the recurring topics include: three-dimensional holographic imaging and applications; recent progresses in computer generated holography; quantitative phase microscopy; three-dimensional display technologies; microscopy for clinical applications; holographic imaging for industrial applications, and advanced processing techniques in digital holography. Some of the novel topics this year include: AI-powered holographic imaging; contemporary imaging techniques; unconventional holographic and QPI techniques and applications; surfaces and materials analysis; holography for high-throughput analysis of dynamic processes; QPI for single-cell analysis; and unconventional holographic imaging systems.
Dr. Nehmetallah—an expert in the fields of computational imaging using machine learning, interferometry, diffraction tomography, holographic/ptychographic microscopy, and metamaterials—has published more than 190 refereed journal papers and conference proceedings and authored a book on the topic of 3D imaging and several book chapters. He is the founder and director of the 3D Optical and Image Processing and Microscopy (3D-OIPM) Lab at the School of Engineering. He is also a senior member of OPTICA (Optical Society of America (OSA)) and SPIE (the international society for optics and photonics), and his research has been funded by NSF, NASA, Air Force, Army, ONR, and DARPA.
Dr. Nehmetallah will travel to Italy in early June, accompanied by his graduate research assistant Quang Trieu; who has supported Dr. Nehmetallah’s research since joining the team in 2022. They will be presenting a paper titled: “Fast Deep Coherence Holography (FDCH) for 3D Object Reconstruction,” where they proposed a fast and position-independent deep-learning-based coherence holography method to reconstruct an object’s shape in three dimensions from two interferograms at a fixed camera location. In addition, Dr. Nehmetallah will present the work of another graduate student on his team, Brad Bazow. This paper, titled, “Three-Dimensional Refractive Index Estimation Based on Non-interferometric Optical Diffraction Tomography with Angular and Axial Illumination Scanning,” discusses the advanced optical capabilities of a microscope system developed in Dr. Nehmetallah’s laboratory. He will present on this computational inverse scattering technique, which allows visualization of biological samples in three dimensions with very high resolution and very high field of view. The technique does not require laser sources or fluorescence staining techniques (which can harm biological samples) and works on live samples allowing visualization of biological dynamical processes in three dimensions in near real time.
