Subaperture stitching measurement for optical components based on the trust region reflective algorithm.

Large-aperture optical surfaces are difficult to measure at full aperture because of the limited aperture of interferometers. Although subaperture stitching can reconstruct the full-aperture surface, its accuracy is often degraded by subaperture positioning errors. To address this issue, we propose TRR-FPC (full phase...
