Bundle center swing caused by rotating joints
Facing the polarization-maintaining fiber collimation head, using the light spot timing and drift as the observation route, the center trajectory corresponding to the rotation angle is intended to be output. 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
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:Requires sampling rate/exposure verification, time synchronization and reference target camera motion compensation; not a substitute for laser Doppler vibrometers. The polarization extinction ratio cannot be demonstrated from the trace. Near-field position and actual coupling efficiency are quantified separately
Route-level gaps:Requires sampling rate/exposure verification, time synchronization and reference target camera motion compensation; not a substitute for laser Doppler vibrometers
"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
Verify aliasing, phase, drift and frame loss with a known frequency shaker or encoder comparison. Use an independent power meter and displacement stage to verify the corresponding position of the coupling efficiency peak
