The shape of the free form cover lens is such that an emission pattern of radiation is emitted without entering into the camera lens and the emission pattern of IR radiation has an asymmetric field of view. Two IR illuminators adjacent to the camera are tilted at an angle from the camera optical direction. The cover lens may be a Fresnel lens, or include a diffractive layer or a collimator to shift radiation emitted from the LED to an asymmetric distribution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"IR illuminator with asymetric radiation pattern","description":"An IR illuminator for providing infrared radiation for a digital camera having a camera lens with a camera field of view, including equidistant mounting substrates arranged adjacent to the digital cam","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11274800","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.
