Wavefront-Based Error Calibration for Coordinate Measuring Machines in the Surface Metrology of Large Optics
Precise measurement of large mirrors is essential for high-performance space-based optics. Traditionally, laser interferometry provides high accuracy but faces challenges related to the requirements of computer-generated holograms (CGHs) and the transformation of standard wavefronts to match complex test surfaces. This...
