Current capabilities and capabilities to be supplemented

Partially reusable

Requires calibration, synchronization or integration

The light point detection front-end or timing statistics module can be reused, but the project still needs to add geometric calibration, time synchronization, motion compensation or equipment system integration.

Gaps in this scenario:Calibration acquisition, coordinate definition and verification are required; two-dimensional empirical mapping does not represent any three-dimensional or robot calibration. The model field diameter model must be defined separately. Near-field position and actual coupling efficiency are quantified separately

Route-level gaps:Calibration acquisition, coordinate definition and verification are required; two-dimensional empirical mapping does not represent any three-dimensional or robot calibration

"Partially reusable" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.

Verification methods and acceptance prerequisites

Separate calibration points and set-out points to check edge, back-and-forth, temperature and repeated clamping errors. Use an independent power meter and displacement stage to verify the corresponding position of the coupling efficiency peak
