Facing the astronomical wavefront test bench, the subaperture light spot and wavefront are used as the observation route, and the subaperture center and matching are planned to be output. The page is for project evaluation and does not mean that the development has been completed or has been accepted on site.

Current capabilities and capabilities to be supplemented
Need to add new core
Need to add core computing
Light point extraction can only be used as an observation front-end, and core capabilities such as three-dimensional reconstruction, closed-loop control, wavefront or physical quantity inversion need to be developed and verified separately.
Gaps in this scenario:Slope conversion, wavefront integration/Zernike fitting and defect reconstruction need to be added; the centroid itself does not output the wavefront. Atmospheric wavefront reconstruction and control are still lacking. Point observation only supports the acquisition/tracking front end, and the data link needs to be implemented independently.
Route-level gaps:Need to add slope conversion, wavefront integration/Zernike fitting and defect reconstruction; the centroid itself does not output the wavefront
"New cores required" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
Verification methods and acceptance prerequisites
Use an independent interferometer or known aberration phase element to verify slope, reconstruction residuals, and dynamic range. Known angle motion table, communication reference and disturbance injection test
