About
Guifeng Chen is a key figure in advancing robotic fiber positioning technology for next-generation astronomical spectroscopy. His research centers on precision mechatronics, calibration methodologies, and control systems for multi-object fiber-fed telescopes—critical infrastructure for large-scale sky surveys. Chen’s major contributions include designing the drive system for a new integrated fiber positioner for the LAMOST upgrade, directly improving observation accuracy and spectral acquisition rates. He also developed a flexible and effective calibration method for fiber viewing cameras, addressing a fundamental challenge: incorrect fiber positioning degrades spectral quality. This work ensures that robotic fiber positioners achieve the sub-micron accuracy required for high-fidelity astronomical data. With over 2 citations each for his most recent papers (2023–2024), Chen’s impact is already evident in the precision instrumentation community. His achievements are particularly notable for enabling the LAMOST improvement project—a major Chinese spectroscopic survey facility—demonstrating his role in bridging innovative design with operational reliability. For students and researchers in astronomical instrumentation, Chen’s work exemplifies how meticulous engineering of positioning and calibration systems directly empowers discoveries in stellar astrophysics and galactic archaeology.
