The apparatus includes a first obtaining unit configured to obtain information about a differential phase image of the object using the information about the interference pattern, a second obtaining unit configured to obtain information about contrast in each region of the interference pattern, a third obtaining unit configured to weight the information about the differential phase image using the information about the contrast to obtain information about a weighted differential phase image, and a fourth obtaining unit configured to integrate the information about the weighted differential phase image to obtain the information about the phase image of the object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Object information obtaining apparatus, program, and imaging system","description":"The present invention relates to an object information obtaining apparatus that obtains information about a phase image of an object using information about an interference pattern produced by a shear","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9702831","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.
