Optical Metrology for Large Space and Terrestrial Telescope Optics

This article is brought to you by: 

Measurement of large optics require metrology systems that can function despite vibration, turbulence and other challenges.Laser interferometry is used throughout the manufacturing of large optics to ensure conformance to demanding design specificationsMore recently, “dynamic interferometry” has been implemented for vibration-insensitive measurement of large optics.
