Peter DiMeo, a senior NSF REU student, integrated high-speed passive autofocus control of high-magnification lenes using nanometer precision piezo actuation in Summer 2021 in Du Lab. This technology was presented in the NSF REU poster competition in the IMECE on Nov. 01-05, 2021, and won Third Place Award. This research is based on Peter’s research report on the poster that won First Place in NSF poster competition in IMECE 2021, and his recent research paper published on Optics Express (https://www.osapublishing.org/oe/fulltext.cfm?uri=oe-29-13-19862&id=451833). This research project is aimed to solve the focus problems in imaging high precision targets, like nano or micro-scale printed patterns in R2R, in high dynamic scenarios that require incredibly fast and precise position control of high-mass and high-magnification lenses. We would like to thank the NSF program directors (Grant: NSF CAREER CMMI-1942185) for funding this REU research.
