Partially reusable
Recording of electrical and thermal drift on laser module
For the semiconductor laser module, the light spot timing and drift are used as the observation route, and the output beam center trajectory and stable waiting time are planned. 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. Synchronous current and case temperature. Pixel grayscale and optical power are calibrated 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.
