A dispersion medium may disperse pulses to form stretched signal pulses that are incident on a substance under test. Optical gating is used to overlap each signal pulse with a portion of a reference pulse to generate a cross-correlation signal corresponding to a portion of the signal pulse, which may be detected by a slow detection speed detector. A controller controls delay introduced to the reference pulses so that different wavelength ranges are sampled for various signal pulses, thereby enabling the entire wavelength range for the signal pulses to be sampled over time without requiring an expensive high-speed optical detector. By analyzing absorption across the entire wavelength range as indicated by cross-correlation signals, the composition of the substance can be identified."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time-wavelength optical sampling systems and methods for determining composition of a sample based on detected pulses of different durations","description":"A time-wavelength optical sampling system may be configured to determine a substance's composition based on variations in optical pulses caused by the substance's absorption of wavelengths of the puls","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11300502","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.
