About

Dr. Hongshen Zhao is a leading figure in precision optical manufacturing, specializing in robotic freeform surface processing and computer-controlled optical surfacing (CCOS). His pioneering work addresses the critical challenge of using industrial robots—rather than traditional CNC machines—for high-precision grinding and polishing of complex optical components. In his most-cited paper (2016, 11 citations), Zhao demonstrated the feasibility of employing a 6-axis Stäubli TX200 robot for CCOS, enabling flexible, cost-effective fabrication of large or intricate freeform surfaces. His subsequent 2017 study (6 citations) systematically analyzed the positioning accuracy of such robotic systems, identifying key error characteristics that degrade grinding precision and efficiency. By quantifying these limitations, Zhao provided essential insights for improving robotic calibration and process control. His research bridges the gap between industrial automation and optical fabrication, offering scalable solutions for advanced optics manufacturing. With a growing citation impact, Zhao’s work is instrumental for engineers and researchers developing next-generation robotic polishing systems, particularly for applications in aerospace, defense, and high-end instrumentation where freeform optics are increasingly vital.
