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:Optical lever geometry, reflection double angle relationship and incident point movement compensation are required; mirror angle and target translation must be separated. The relationship between the roller body geometry and the assembly target needs to be calibrated. Point measurement coverage is determined by the sampling spacing
Route-level gaps:Optical lever geometry, reflection double angle relationship and incident point movement compensation are required; mirror angle and target translation must be separated
"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
Use an independent angle stage/autocollimator to conduct bidirectional and multi-attitude tests, and report the angle error and return difference. Repeated measurements of thick sheets, standard rolls and speed steps
