Current capabilities and capabilities to be supplemented
Reusable modules
Existing modules can be used as hosts
Existing light point positioning, quality diagnosis or statistical modules can be used as the main calculation basis; ROI, calibration, threshold and interface verification still need to be completed by device.
Gaps in this scenario:Pixel scale, background subtraction and dynamic range verification required; grayscale integration is not watts or joules. The components of biological tissue cannot be determined from the light spot. Particle image positioning is an algorithm migration and the image model must be re-verified.
Route-level gaps:Pixel scale, background subtraction and dynamic range verification required; grayscale integration not watts or joules
"Reusable modules" only describe the relative development volume and do not constitute a commitment to accuracy, tempo, stability or delivery time.
