The system also includes lensing optics to emit the combined beam towards a target and collect light returned from the target in a return optical beam to be received by the first beam splitter. The first beam splitter demultiplexes the return optical beam into a first return beam and a second return beam having orthogonal linear polarizations. The system also includes an optical element to generate a first beat frequency from the first return beam and to generate a second beat frequency from the second return beam. The system also includes a signal processing system to determine a range and velocity of the target from the first beat frequency and the second beat frequency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Techniques for determining speed and distance to objects using coherent LiDAR","description":"A light detection and ranging (LiDAR) system that includes a first beam splitter to multiplex a first optical beam and a second optical beam into a combined beam having orthogonal linear polarizations","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11486975","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.
