SG II Team Makes Progress in Large-Gradient Wavefront PSD Measurement Based on Knife-Edge Scanning Filtering
Oct 30, 2025
Researchers from SG II facility has made progress in measuring the Power Spectral Density (PSD) of large-gradient wavefronts. The team proposed a wavefront detection method based on knife-edge scanning filtering, which enables precise detection of mid-to-high spatial frequency errors in wavefronts with large gradients.
