The clipped portions of the signal are reconstructed using tangential adjacent point spread functions as a reference or adjacent channel ratios as reference. Multichannel camera detectors having unique response magnitude ratios per wavelength are exploited to make associated direct mappings, thereby making improvements in wavelength resolution and accuracy to up to at least one to two orders of magnitude."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical spectrometer with enhanced spectral resolution from an unregistered tristimulus detector","description":"A spectrometer includes a spectrogram, digital camera and signal processing to compensate for limits of system spatial resolution, spatial distortions and lack of precision spatial registration, limit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9736400","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.
