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. Not used as a specimen strain measurement. Forces, moments and strains must be mechanically modeled and independently calibrated

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. Weights, standard force sensors and multiple loading return comparisons
