NUC coefficients such as offset and/or gain are applied to either the output signals of the detector or to the image to form the NUC'd images. In a calibration mode, the mirrors are tipped and tilted and/or pistoned to spatially or temporally blur the image or to re-direct the FOV to one or more on-board calibration sources to generate a uniform image from which to calculate and update the NUC coefficients."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical non-uniformity compensation (NUC) for passive imaging sensors using micro-electro-mechanical system (MEMS) micro-mirror arrays (MMAS)","description":"A passive imaging sensor includes a plurality of optical elements in which at least one includes one or more Micro-Electro-Mechanical System (MEMS) Micro-Mirror Arrays (MMAs) having a plurality of ind","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11483500","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.
