Validating metrology techniques for opto-mechanical error measurement of heliostats: next steps
20 August 2024 • 9:20 AM - 9:40 AM PDT | Conv. Ctr. Room 18
Abstract
This paper follows the pathway that is recommended in the HelioCon report, "Roadmap to Advance Heliostat Technologies for Concentrating Solar-Thermal Power" to address the Tier 1 gaps identified in metrology and standards. Most of these gaps are related to missing commercialized metrology to measure opto-mechanical errors of heliostats. Cross-validation of metrology techniques that are available or under development is needed. The authors evaluate the state of the art of those metrology techniques and outline a Round Robin Test plan based on the results. The goal is to initiate the next step in closing the Tier 1 gaps in metrology.

Stephanie Meyen
National Renewable Energy Lab. (United States)
Stephanie Meyen is known to the CSP research community from her earlier work at the DLR Institute of Solar Research in Cologne, Germany and at the Plataforma Solar de Almeria in Spain. She was an active member in the founding of the QUARZ and OPAC laboratories and the main author of the original Solar Paces Reflectance Measurement Guideline.
During the last 9 years, Ms Meyen has expanded her horizons in the USA, in a more industrial manufacturing setting. She worked on 3D Flash Lidar systems designed to go into space on the OSIRIS-REx sample-return probe and the Boeing CST-100 Starliner.
Then she advanced the optical metrology capacity at the Richard F. Caris Mirror Lab by leading the integration of high-precision deflectometry systems. These guide the manufacturing of the world's largest telescope mirrors for the Giant Magellan Telescope and others.
Recently Ms Meyen decided to join NREL to resume her work in advancing commercial CSP technology.
