The ultra-weak light multispectral two-dimensional imaging system realizes high-resolution optical modulation by adopting the compressive sensing (CS) theory and the digital light processing (DLP) technology and using a linear array single-photon detector as a detection element; the ultra-weak light multispectral two-dimensional imaging system comprises a light filter, a first lens (1), a DMD control system, a second lens, a spectrophotometer, a linear array single-photon detector consisting of a plurality of single-photon detectors with different response wavelengths, and a central processing unit; and the sensitivity of the system can reach the single-photon level. The invention can be widely applied in the fields of biological self-illumination, medical diagnosis, nondestructive material analysis, astronomical observation, national defense and military, spectral measurement, quantum electronics and the like."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-spectral imaging method for ultraweak photon emission and system thereof","description":"An ultra-weak light multispectral imaging method and an ultra-weak light multispectral imaging system, which can realize multispectral two-dimensional imaging of an ultra-weak light object by constitu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9807317","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.
