A distance measuring device (1) includes an illumination unit (1) that illuminates using multiple modulated light having a plurality of frequencies satisfying a relationship in which one frequency is an even multiple of another frequency, a light receiving unit (20) that accumulates the charge of reflected light of the multiple modulated light into a plurality of accumulation units while switching an accumulation unit into which the charge is accumulated at a predetermined timing, and a distance calculation unit (30) that calculates a distance based on the charge."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distance measuring device, distance measuring method, program, and integrated circuit","description":"A distance measuring device using a multiple wave enables measurement of long distances with a high resolution and with a high precision by significantly reducing the circuit scale required for demult","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531651","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.
