On the basis of the wavelength of scanned reflection light and the location of the pixel in a light reflection state at a timing of acquisition of output, the relationship between the x coordinate of the wavelength selection element and wavelength is determined. This makes it possible to achieve calibration of the optically variable filter array apparatus capable of selection of a desired wavelength with respect to a desired channel from multi-channel WDM light."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for calibration of optically variable filter array apparatus","description":"In a wavelength selection element employed in an optically variable filter array apparatus, pixels in a line form are placed into a light reflection state so that wavelength-scanned light can be incid","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488229","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.
