Welcome to Analytical 3D Optical Sensing Laboratory (3DAOS)!

The 3DAOS lab is located at Iowa State University in Ames, Iowa. We have three major missions: (1) Innovating technologies for accurate high-dimensional data acquisition; (2) developing novel analytics tools to generate insights from 3D data; (3) applying developed 3D optical sensing technologies to different fields. Our research has achieved breakthroughs including the first-ever dense 3D strain measurement technology for robotic flapping wings. The interdisciplinary nature of our research opens up opportunities for research collaborations, including areas such as robotics, advanced manufacturing, materials mechanics testing and so forth.
