The detector is arranged such that its rows are inclined to an image of a vertical axis of the object by an acute angle. A method of detecting a height difference of an apparatus relative to a leveling staff includes imaging the leveling staff onto an array of detectors such that the image of a vertical axis of the staff is inclined to detector rows at an acute angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Leveling apparatus and method","description":"A leveling apparatus for optically detecting a height difference relative to a leveling staff includes an objective, a two-dimensional detector, a mount for rotating both the objective and the detecto","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537216","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.
