Laser Metrology System for Large Space Optics

High-resolution imaging of expansive areas on Earth necessitates large aperture optical systems operating from higher orbital altitudes. While monolithic primary mirrors present a limited solution set, segmented optics offer a potentially more cost-effective and rapidly deployable alternative. This research and development project addresses a critical enabling technology for such large aperture segmented systems: the ability to precisely measure and maintain the alignment and figure of space-based optics constructed from multiple, low-cost mirror segments. Our innovative Laser Metrology System provides high-accuracy measurement of individual mirror segment locations. By achieving and preserving a precise optical figure across the entire aperture, a single space-based imager can achieve significantly wider coverage areas while maintaining the resolution of current commercial systems
