Attend the Advanced Optical Methods for Manufacturing and Metrology seminar, April 11
Join the School of Manufacturing Systems and Networks for the Advanced Optical Methods for Manufacturing and Metrology seminar.
Abstract
The development of advanced optical systems for space, semiconductor and additive manufacturing applications relies on the precise coordination between fabrication processes and high-resolution metrology. Meeting the stringent structural, optical and system-level performance requirements demands integrated solutions that blend manufacturing innovation with scalable, in-situ inspection techniques. This talk presents recent advances in optical fabrication and metrology, starting with CNC-based post-processing of freeform optics for space telescope applications. It then introduces the development of a stroboscopic stereovision system for real-time, on-machine monitoring. To enable even finer-scale accuracy, compact interferometric units — originally designed for gravitational wave detection and capable of picometer-level displacement sensing — are being adapted for broader use in optical metrology. Ongoing work focuses on the design, fabrication and characterization of mirror structures, including lightweight configurations, with integrated metrology embedded throughout the process. The talk also explores emerging opportunities in vision-based and interferometry-driven inspection methods for next-generation manufacturing systems.
About the speaker
Xiangyu Guo is an assistant professor in the School of Manufacturing Systems and Networks at Arizona State University. She earned her master’s degree in optical science from the University of Arizona in 2019 and her doctoral degree in mechanical engineering from Texas A&M University in 2022. Following her doctoral studies, she served as a postdoctoral research scholar in the Laboratory of Space Systems and Optomechanics within the Department of Aerospace Engineering before returning to the University of Arizona. Today at ASU, Xiangyu leads the Systems, Optics and Laser Application Research, or SOLAR Lab, where her research focuses on precision metrology methods for manufacturing process control. Her work emphasizes interferometry, machine vision and advanced materials. She also advances the design and fabrication of engineered material structures — such as lightweight 3D mirrors — integrating post-fabrication analysis and system-level monitoring to enable next-generation manufacturing technologies.
