About

Fengtao Yan is a specialist in advanced optical fabrication, with a primary focus on the precision manufacturing of silicon carbide (SiC) aspheric mirrors. His most cited work, "Fabrication of SiC Off-axis Aspheric Mirror by Using Robot Polishing" (2019), demonstrates his expertise in combining computer-controlled optical surfacing (CCOS) with robotic polishing to produce complex, lightweight mirrors. In this study, Yan successfully fabricated two SiC off-axis aspheric mirrors—a 380mm × 328mm primary mirror and a 294mm × 238mm tertiary mirror—achieving high surface accuracy through an innovative process that integrates deterministic material removal with robotic flexibility. This contribution is critical for next-generation telescopes and space optics, where SiC’s high stiffness-to-weight ratio and thermal stability are essential. While his citation count (3) reflects a specialized niche, his work represents a practical advancement in cost-effective, scalable fabrication of large, lightweight optics. Yan’s research bridges the gap between traditional polishing and modern automation, offering a pathway for producing high-performance mirrors for aerospace and astronomical applications.
