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. Differentiation and filtering delays must be verified. The relationship between the mirror target, the receiving target and the machine tool datum must be measured

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. Ruler/autocollimator/independent geometric measuring tool and two-way travel comparison
