Quick Answer:
Short Answer
Roll-2-Roll® Sensors use spatial light filtering that automatically adapts to any material properties.
Roll-2-Roll® Sensors use patented fiber-optic technology with adaptive edge detection algorithms. Unlike ultrasonic sensors that measure sound reflection (affected by material density and porosity) or simple infrared sensors that require threshold adjustment, [rr sesors] use spatial light filtering to detect edges regardless of material properties. The sensor automatically adapts to different reflectivity, transparency, and surface characteristics—whether running clear films, opaque substrates, metallic foils, or porous nonwovens.
