Professor Ellis recently met with Professor Jui-Wen Pan and Dr. Kao-Der Chang who were on a visit to The Institute of Optics Industrial Associates Program from Taiwan and discussed methods for transitioning technology from the university environment to relevant industries. Professor Pan is an Assistant Professor in the Institute of Photonic System at the National Chiao Tung University. Dr. Chang is a Researcher at the Industrial Technology Research Institute (ITRI) in their Mechanical and Systems Research Laboratory. We look forward to potential collaborations in the future!
Fenghe hails from Wuhan, China from Huazhong University of Science & Technology with a background in opto-electronics. He is currently pursuing his MS Thesis research in The Institute of Optics.
Elizabeth is currently a BS student in Mechanical Engineering at the University of Rochester. She is originally from Chapel Hill, NC and is interested in precision engineering and opto-mechanical design.
Dr. Tieli Zhang‘s stint at the University of Rochester as a Visiting Scientist in the Department of Mechanical Engineering has ended. We wish Dr. Zhang all the best in the future!
Also, we welcome UR MechE Alumnus Tim Lynch into the group as a MS Student working on Freeform Optics Metrology. Welcome, Tim!
Xiangzhi Yu, mechanical engineering PhD student, is defending his PhD Thesis Proposal today, Monday, December 14 at 1 PM. The location for his Proposal Defense is in Hopeman 224.
Precision linear stages provide the basic movement for many nanotechnology systems such as lithography stages, biological scanning systems, and nanofabrication positioning systems. All these systems require precise position sensing for feedback control and extensive calibration procedures to achieve the required accuracy. In this proposal, a compact state-of-the-art multidegree of freedom optical metrology system is presented which will enable fast, accurate calibration and error mapping of multiple axes simultaneously. The working principle for each degree-of-freedom measurement is shown and system-level integration will be investigated to evaluate the overall performance. In addition, the proposed system will significantly mitigate the temporal, dynamic, location and Abbe errors during calibration process. In the end, a refractometer which enables both absolute refractive index of air sensing and tracking based on variable length vacuum cell is presented, which is essential for ultra-precision interferometry measurements under atmospheric conditions.
Steve Gillmer, MechE PhD student, was awarded the 2015 Carl Zeiss Student Scholarship at the recent American Society for Precision Engineering Annual Meeting. This award includes the ASPE Annual Meeting registration fee, four tutorial fees, travel expenses, and lodging to the Annual Meeting. In addition, the scholarship provides for travel and lodging to Maple Grove, Minnesota to visit Carl Zeiss Industrial Metrology. Steve is the third recipient of the Carl Zeiss Student Scholarship awarded through ASPE.

Xiangzhi Yu, MechE PhD student, has been part of the winning team at the ASPE Student Competition for the second time. Xiangzhi, along with teammates Andrew Duenner, Ian Ladner, Nilabh Kumar Roy, and Tsung-Fu Yao from the University of Texas at Austin won the ASPE Student Competition at the Annual Meeting of the American Society for Precision Engineering. The students were tasked with building a closed loop controlled X-Y scanning system to image an area the size of a penny using MechBlocks, voice coils, capacitance sensors, and motion controllers in about 9 hours of work. Each winning student was awarded a $1,000 prize and a stainless steel MechBlock kit from MOTUS Mechanical. Congratulations Xiangzhi!
