Beiwen Li, Ph.D.

Intelligent 3D Optical Sensing for In-Situ Applications

April 29 | 4:00 pm | Zoom Seminar

Assistant Professor, Mechanical Engineering, Iowa State University


The recent advances of 3D optical sensing have realized an unprecedented combination of kilohertz measurement speeds and tens of micrometer accuracies. However, multiple challenges are still present before it will be widely adopted. This talk mainly focuses on our recent research advancements in addressing some long-standing challenges in highspeed 3D optical sensing and our ongoing effort of exploring its feasibility as an in-situ non-destructive evaluation tool for manufacturing and other applications.


Dr. Beiwen Li is an Assistant Professor of Mechanical Engineering and the director of Analytical 3D Optical Sensing Laboratory at Iowa State University. He received his Ph.D. degree in Mechanical Engineering from Purdue University in 2017. His research focuses on superfast kilohertz 3D optical sensing, precision 3D optical metrology, 3D point cloud data analysis and insitu monitoring for additive manufacturing. Several of his research works have been highlighted on the cover page of prestigious journals including Optics Express, Applied Optics and Géotechnique Letters. He is the recipient of 2020 SPIE Defense & Commercial Sensing Rising Researcher Award.
