About

The Optical Metrology Group (OMG) at IASBS is a hands-on, research-driven team dedicated to advancing precision optical measurement and imaging. Our group combines experimental particularity with innovative approaches to develop cutting-edge instruments and techniques for surface profiling, holographic microscopy, and biomedical imaging. We emphasize collaborative, practical learning: members actively engage in experiments, prototype development, and data analysis. Weekly group meetings provide a platform for sharing progress, discussing challenges, and planning upcoming projects. Whether you are a researcher, student, or collaborator, OMG provides a dynamic environment where ideas are transformed into tangible results. Group Meetings:

$Dr. Ehsan A. Akhlaghi is an Associate Professor in the Department of Physics at the Institute for Advanced Studies in Basic Sciences (IASBS), Zanjan, Iran, and the founder and director of the Optical Metrology Group (OMG). He earned his B.Sc. in Solid State Physics from the University of Tehran (2003), M.Sc. in Optics from the University of Zanjan (2006), and Ph.D. in Optics from IASBS (2011). Since establishing OMG in 2012, he has focused on integrating fundamental optical science with practical applications in biomedical imaging, industrial metrology, and advanced optical instrumentation. His research interests span optical metrology, 3D imaging and microscopy, super-resolution microscopy, digital holography, optical coherence tomography (OCT), diffractive optics, structured light generation, biomedical imaging and spectroscopy, image processing, and microfabrication. He has designed and implemented high-precision optical systems for both fundamental studies and applied research, including surface profiling, quantitative phase imaging, and optical biosensing.$

Beyond academia, Dr. Akhlaghi is the co-founder and managing director of Fath Noor Mihan (FathOptics), co-founder of Engareh Physics Toos Knowledge-Based Company, and COO of Interactive Intelligent Process Automation Inc. His industrial collaborations have resulted in the development of knowledge-based instruments such as optical profilometers, spectrometers, spatial light modulators, and nano-positioners, supporting applications in precision manufacturing, biomedical diagnostics, and environmental monitoring. He has supervised numerous Ph.D. and M.Sc. theses in advanced optical imaging, spectroscopy, and applied photonics, and has published in leading journals such as Optics Express, Optics Letters, and Scientific Reports. His achievements include recognition as the Top Technologist of Zanjan Province (2018).

Founded in 2012, the Optical Metrology Group (OMG) at IASBS has grown into a leading team in precision optical measurement and imaging. Over the years, the group has developed advanced instruments, including 3D nano-profilometers, spectrometers, and spatial light modulators. OMG’s work spans fundamental research and applied science, contributing to high-resolution 3D imaging, biomedical diagnostics, and environmental monitoring. Its results have been published in top-tier journals and translated into knowledge-based products for scientific and industrial applications.

OMG actively collaborates with national and international universities, research institutes, and industry partners. These partnerships facilitate interdisciplinary research, provide access to specialized facilities, and enable the translation of scientific findings into practical solutions. The group continuously seeks new collaborations and joint projects to expand its scientific and industrial impact.
