Exploring the Future of Metrology at CMSC 2026
The Coordinate Metrology Society (CMS) has announced a standout keynote for the 2026 Coordinate Metrology Society Conference (CMSC), bringing a unique perspective that bridges precision engineering and astronomical discovery. Dr. Sandrine J. Thomas, Rubin Associate Director for Summit Operations at the Vera C. Rubin Observatory, will take the stage in Dallas to explore how metrology underpins one of the most ambitious scientific programs ever undertaken.
Dr. Thomas leads the team responsible for acquiring all data for the Legacy Survey of Space and Time (LSST), including raw imagery, calibration datasets, and critical telemetry. Her work operates at the intersection of physical optics, adaptive systems, and large-scale data acquisition—fields where precision is not just important, but mission-critical.
Precision Beyond the Shop Floor
At the Rubin Observatory, metrology transcends traditional boundaries. Measurement is no longer confined to millimeters or even microns in isolation, but instead spans vast, interconnected systems operating in extreme environmental conditions. From aligning advanced optical assemblies to maintaining calibration stability across a telescope designed to image the entire southern sky, the challenges are both immense and unforgiving.
Dr. Thomas’ career reflects deep expertise in physical optics, active and adaptive optics, and coronagraphy. Prior to her current role, she worked extensively on major telescope systems located in Chile, including CTIO, SOAR, and Gemini, and held research positions at the University of California, Santa Cruz and NASA Ames. She earned her PhD from the University of Nice Sophia Antipolis.
Her keynote will highlight how foundational principles of dimensional metrology, familiar across manufacturing and inspection, are applied at a cosmic scale. Attendees can expect insights into:
- Maintaining alignment and accuracy across large, complex systems
- Managing environmental variables that influence measurement precision
- Scaling metrology processes to support massive data acquisition
- Ensuring repeatability and reliability in extreme operating conditions
The session promises to demonstrate that the same measurement disciplines ensuring quality on the shop floor are also enabling groundbreaking advances in astronomy.
A Conference Shaping the Future of Measurement
Taking place from July 20–24, 2026, at the Fairmont Dallas, CMSC 2026 marks the 42nd annual gathering of the global metrology community. The event continues to serve as a premier platform for 3D measurement, inspection, and precision engineering technologies.
This year’s conference will feature:
- Technical presentations from leading experts across industries
- Hands-on workshops and certification opportunities
- Live demonstrations of the latest metrology hardware and software
- Exhibitions showcasing innovations in laser scanning, CMMs, automation, and AI-driven inspection
- Extensive networking opportunities with industry leaders and innovators
With participants spanning aerospace, automotive, energy, defense, and advanced manufacturing sectors, CMSC provides a vital forum for knowledge exchange and collaboration.
Join the Conversation
With early bird registration open through May 20, CMSC 2026 is set to be one of the most impactful gatherings in precision measurement. Dr. Thomas’ keynote underscores a powerful message: metrology is not just a tool for manufacturing – it is a fundamental enabler of discovery, pushing the limits of what is measurable, achievable, and ultimately, knowable.
From micron-level tolerances to the vast scale of the universe, the principles remain the same. CMSC 2026 invites attendees to explore those connections and be part of the evolving future of precision.
