AI Technical Summary
Technical Problem
Optical-fiber connector inspection microscopes face challenges in reliably detecting small defects like dust and scratches on multi-fiber connectors due to non-uniform illumination and mechanical imperfections, leading to saturation and double image artifacts.
Method used
Activating illumination sources in sequence to prevent overlap and capturing images separately to ensure uniform illumination, with additional cross-illumination images to address tilted connector issues, allowing for accurate defect detection.
Benefits of technology
This approach results in more uniformly lit images with reduced dark spots and double image artifacts, enhancing the ability to detect small defects on multi-fiber connectors.
