The at least one light source comprises a waveguide which vertical decouples light; a first linear polarizer arranged between the light source and the image sensor; and a ring-shaped second linear polarizer arranged over the light source to polarize light emitted by the light source in a direction away from the image sensor and having an opening which allows light reflected by a biometric object to reach the lens without being filtered by the second linear polarizer. At least one of the polarizers are rotatable."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Biometric imaging device comprising polarizers","description":"An optical biometric imaging device includes an image sensor having a plurality of photodetector pixels; a lens assembly having at least one lens configured to focus light reflected by a biometric obj","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11995911","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.
