About

Le Shen is a leading researcher in precision optical manufacturing, specializing in robotic polishing of large, complex optical surfaces. His work focuses on overcoming the challenges of fabricating heavy-calibre off-axis aspheric mirrors and composite mirrors, where traditional polishing methods fall short. Shen’s major contributions include pioneering the use of industrial robots—such as the ABB IRB6640—as flexible, high-precision polishing platforms. He has developed critical algorithms for coordinate transformation, Euler angles, and quaternion representation, enabling accurate tool-path control. His innovative use of M-like and Gaussian-like removal functions allows for controlled material removal, effectively addressing issues like honeycomb print-through in NiP/Cu coated carbon fiber composite mirrors. With his most cited works accumulating over a dozen citations, Shen’s research is gaining recognition for its practical impact on advanced optics manufacturing, particularly for defense and aerospace applications. His work on robot-arm wheel polishing represents a significant step toward automating the production of large, high-quality mirrors, reducing costs and lead times while improving surface accuracy.
