Optical axis drift inspection after collimator locking
Facing the optical fiber collimator, taking the spot shape and relative distribution as the observation route, it is intended to output the center and axis ratio before and after locking. 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
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. Mechanical clamping stresses need to be recorded. Near-field position and actual coupling efficiency are quantified separately
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. Use an independent power meter and displacement stage to verify the corresponding position of the coupling efficiency peak
