Optical Manufacturing and Testing of Large-Aperture Optical Mirrors: A Review
Large-aperture optical mirrors are critical to astronomical observation, and their fabrication requires full-chain technologies spanning blank preparation, deterministic polishing, cross-scale metrology, and acceptance testing. A review highlights a closed-loop manufacturing-testing paradigm for continuous surface-error correction, while identifying sub-nanometer full-frequency precision control, intelligent adaptive integration, and in-orbit manufacturing as key directions for future ultra-large-aperture mirrors.
