Embodiments are described wherein the multiplexer and the demultiplexer may comprise FDM or OFDM, and wherein both the excitation light and the emitted light may be encoded using a DMA or a SLM. In some embodiments the same DMA or SLM may be used to encode the excitation light and the emitted light. In some embodiments excitation light may be encoded using a Walsh function, or the excitation light may be encoded using a Walsh function and the emitted light may be decoded using an inverse Hadamard transformation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiplexed excitation emission matrix spectroscopy","description":"Described herein is an excitation emission matrix (EEM) spectrometer and method, comprising a multiplexer that encodes excitation light produced by at least one excitation light source; and a demultip","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10481092","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.
