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:New system identification, controller, delay budget and lock loss processing need to be added; the existing module only provides position observation. Double receiving surface decoupling and controller are required. Position observation and execution control must be independently accepted
Route-level gaps:New system identification, controller, delay budget and lock loss processing need to be added; the existing module only provides position observation
"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
Verify tracking error, overshoot, stability, loss of lock and recovery with step/sweep and perturbation injection. Set aside points, steps and sweeps to verify delays and loss of lock
