About

Davide Fierro is a key figure in astronomical instrumentation, specializing in active optics and precision telescope control systems. His research focuses on the development and performance optimization of adaptive secondary mirror support systems for large ground-based telescopes. Fierro’s major contributions center on the Very Large Telescope Survey Telescope (VST), where he pioneered the use of a hexapod—a six-degree-of-freedom parallel robot—to actively control the secondary mirror. This innovation enables real-time correction of defocus and coma, dramatically improving image quality. His most-cited work, “Active optics control of VST telescope secondary mirror” (2010, 21 citations), details this breakthrough application, while his follow-up study “Performance of the VST secondary mirror support system” (2010, 12 citations) validates the system’s reliability. Together, these papers have shaped modern active optics design, influencing next-generation survey telescopes. Fierro’s work demonstrates how precision mechatronics can overcome atmospheric and gravitational distortions, making him a respected authority in optomechanical engineering for astronomy.
