The device includes a transparent substrate, a marker pattern directly formed on the transparent substrate and extending in a direction non-parallel to the main scanning direction of the two-dimensional scanning, and fine uneven structures formed on the marker pattern and the transparent substrate where at least the surface is made of a metal film."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Measuring apparatus where a distance between a surface of a transparent substrate on which a marker pattern is formed and a front surface is within a depth of focus of a detecting means","description":"An optical electric field enhancing device is used with a measuring method which includes two-dimensionally scanning a surface in in-plane direction of the surface to detect, from the rear surface sid","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9645087","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.
