The spacing between the phase modulation element and the image sensor is set so that the duty ratio of the full width at half maximum for a bright section to the width for one period of a projection image of the concentric grating pattern is 0.5 or less in the case of light incidence from a point light source disposed at a distance of a subject in the axial direction of a concentric circle of the grating pattern."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging device","description":"An imaging device includes: an image sensor that outputs, as an image signal, light received at a light-receiving surface; a phase modulation element provided in close to the light-receiving surface, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10488561","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.
