About

Laurent Marty is a leading expert in active optics for ground-based telescopes, with a career focused on the design and control of precision positioning systems that correct optical aberrations in real time. His most significant contributions center on the Very Large Telescope Survey Telescope (VST) at ESO’s Cerro Paranal Observatory in Chile. Marty pioneered the use of parallel robots—specifically hexapods with six degrees of freedom—to actuate the telescope’s secondary mirror, enabling rapid, sub-micron corrections of defocus and coma. His work, detailed in highly cited papers such as “Active optics control of VST telescope secondary mirror” (21 citations) and “The VST secondary mirror support system” (18 citations), demonstrates how these robotic systems replace traditional mechanical linkages, achieving unprecedented stability and precision. By integrating wavefront sensor feedback with hexapod control, Marty’s research has directly enhanced image quality for wide-field surveys. His 2007 theoretical and experimental study on parallel robots in active optics remains a foundational reference. With over 50 cumulative citations, Marty’s engineering innovations have made the VST a benchmark for active optics, influencing next-generation telescope designs and cementing his reputation as a key figure in astronomical instrumentation.
