A surface of the personalized document is illuminated independently or simultaneously by first and second light sources. The first light source has a ring shape, surrounds the personalized document in 360 degree, and transmits a grazing incident light to illuminate the surface of the personalized document. An incident light from the second light source is reflected by a beam splitter and illuminates the surface of the personalized document in a direction generally perpendicular to the surface. Light reflected from the surface of the personalized document in a direction generally perpendicular to the surface thereof is collected by a camera."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Machine vision verification","description":"Embodiments of systems and methods for directly reading and verifying characters on a personalized document, are provided.
