The tracker further comprises a beam directing unit pivotable by motor power, which defines a vertical pivot angle for orienting the measuring radiation and for receiving measuring radiation, an angle measuring functionality for determining the horizontal pivot angle and the vertical pivot angle, a distance measuring functionality and a photosensitive surface detector for detecting an incidence position of the reflected measuring radiation. The base has a self-calibration unit with a first retroreflective reference target and an optical assembly functioning as a reducing lens."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Laser tracker with calibration unit for self-calibration","description":"Embodiments of the invention relate to a laser tracker for continuous tracking of a target, with a beam source for generating measuring radiation, a base defining a vertical axis and a support, wherei","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9766326","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.
