The measuring step measures a first transmitted wavefront for a first wavelength and a second transmitted wavefront for a second wavelength different from the first wavelength. The calculating step calculates the refractive index distribution of the test object by removing a shape component of the test object utilizing measurement results of the first and the second transmitted wavefront, and a transmitted wavefront of a reference object arranged in the medium for each of the first and second wavelengths. The reference object has the same shape as the test object and a specific refractive index distribution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Refractive index distribution measuring method and refractive index distribution measuring apparatus","description":"A method includes measuring a transmitted wavefront of a test object by introducing reference light into the test object arranged in a medium having a refractive index different from a refractive inde","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472014","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.
