Verification statusThe actual machine/product domain acceptance of this scenario has not been carried out
Migration instructions:The migration of positioning algorithms for non-laser sun spots should not be represented as a proven application for laser products. The potential application scenario has not yet been developed into a complete product system; the actual machine/product domain acceptance of this scenario has not been carried out. The actual product/product domain acceptance quantity in catalog statistics is 0.

Current capabilities and capabilities to be supplemented
Reusable modules
Existing modules can be used as hosts
Existing light point positioning, quality diagnosis or statistical modules can be used as the main calculation basis; ROI, calibration, threshold and interface verification still need to be completed by device.
Gaps in this scenario:Pixel scale, background subtraction and dynamic range verification required; grayscale integration is not watts or joules. Non-laser spot; radiation calibration and multi-peak processing need to be added. Geometric and spot indicators do not replace electrical performance or equipment fault diagnosis.
Route-level gaps:Pixel scale, background subtraction and dynamic range verification required; grayscale integration not watts or joules
"Reusable modules" only describe the relative development volume and do not constitute a commitment to accuracy, tempo, stability or delivery time.
Verification methods and acceptance prerequisites
Verify center, width and cutoff separately against a stand-alone beam analyzer or known spot pattern. Displacement meter, beam meter and design target cross comparison
