Abstract
Machine vision systems are provided. More specifically, machine vision systems are provided that incorporate polarized illumination and detection. Polarized electromagnetic radiation may be used to reduce glare and enable increased flashing speed in machine vision detection systems. Ultra-high power light sources, heat tolerant polarizing media and optical-path systems may be coupled with ultra-high speed flashing systems to enable increased web-speed while maintaining necessary accuracy in web-scanning operations.
