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:Snell/ray tracing and parameter identifiability analysis need to be added; deflection cannot uniquely prove composition or concentration. Thickness or internal stress cannot be given directly. Material optical properties need to be included in calibration and failure conditions
Route-level gaps:Snell/ray tracing and parameter identifiability analysis need to be added; deflection cannot uniquely prove composition or concentration
"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
Examine geometry/composition cross-sensitivity using a known prism or refractive index reference medium and controlled temperature. Standard parts and contact gauges are crossed to test different surface conditions
