A contrast enhancing layer is provided with one contrast shield associated with each light-sensitive element of the sensor layer. The associated contrast shield is arranged at a distance above the light-sensitive element and has a surface area at least as large as an active region of the light-sensitive element). The contrast shield is arranged at a distance above the light-sensitive element such that at least 60% of the active region is covered. The illumination layer has a plurality of point light sources which emit in direction of the placement surface in an angular area limited for preventing total internal reflection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for the direct optical capture of skin prints and documents","description":"An apparatus for direct optical capture of security-relevant objects such as at least skin prints and documents produces a contrast between skin ridges and skin valleys in direct optical sensors for c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11238264","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
