About

Dr. Christina Reynolds is a leading figure in precision optical fabrication, specializing in the deterministic manufacture of freeform optics. Her research addresses critical challenges in sub-aperture polishing, particularly the removal of mid-spatial frequency (MSF) errors—a notorious obstacle that degrades optical performance. Her most cited work (28 citations) presents an effective process chain for polishing aluminum free-form mirrors, directly tackling the tool-misfit issues that plague these complex surfaces. Dr. Reynolds has also made significant contributions to process automation and tool path generation. She developed a novel hyper-crossing tool path algorithm, leveraging Voronoi diagrams and pseudo-random patterns to improve polishing uniformity and efficiency. Her forward-looking work on "Industrie 4.0" for optical fabrication has explored the complementary roles of robots and CNC machines, demonstrating automated part handling between polishing and metrology stations. By combining fundamental insights into material removal with practical automation strategies, Dr. Reynolds is driving the transition toward fully automated, high-precision optical manufacturing, with direct impact on the production of advanced mirrors for aerospace and defense applications.
