The scanning unit includes a light source, a scanning grating disposed on a first side of a transparent carrier element that is positioned in a scanning beam path and a detector arrangement. The scanning unit further includes an attenuation structure that adjusts a light intensity on the detector arrangement in a defined manner, wherein either 1) the attenuation structure is disposed on a second side, opposite the first side, of the transparent carrier element or 2) the attenuation structure has a permeability that varies as a function of location at least along one direction so that a light intensity which is uniform at least in that one direction results on the detector arrangement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical position measuring device","description":"A measuring device for detecting a relative position, the measuring device including a measurement graduation movable in at least one measurement direction and a scanning unit for determining a relati","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537370","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.
