Xiaoping Qian, assistant professor of mechanical and aerospace engineering, is the principal investigator on several projects sponsored by the National Science Foundation, the Air Force Office of Scientific Research, the Society of Manufacturing Engineers Education Foundation, and General Electric, among other agencies. He is working with a group of five Ph.D. students, primarily on two areas of research.
His study in atomic force microscope-based nano-imaging and nano-manipulation aims to understand and correct the dimensional bias in AFM imaging of nano-structures. Successful completion of this research will positively impact the entire spectrum of industries that use AFM such as semiconductor, data storage, MEMS, and molecular imaging industries. It will thus provide a metrological basis for nano-scale manufacturing.
Dr. Qian’s project on integrating multiple 3D sensors for efficient digitization of complex 3D objects intends to develop a next-generation system for autonomous construction of digital models from physical objects. The ability to obtain a digital geometric model directly from physical objects marks a revolutionary step in the information era. Three-dimensional (3D) digitization is a process to create three-dimensional computer models of a physical object. Such reconstructed 3D shape models have become indispensable in a variety of applications such as product design and manufacturing in aerospace, automotive, and die and mold industry, patient-specific medical device design and analysis, as well as target recognition and scene understanding in homeland security and military applications.
