The LED device emits a light with a wavelength centered on an absorption line of the target detection non-solid substance, and also emits a reference line with a wavelength that is not absorbed by a target non-solid substance, while both wavelengths are transmitted through the atmosphere with low loss. Since the absorption and reference wavelengths are emitted from the same exact aperture, both wavelengths can share the same optical path, reducing the size and cost of the detector while also reducing potential sources of error due to optical path variation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bi-directional dual-color light emitting device and systems for use thereof","description":"An LED optimized for use in low-cost gas or other non-solid substance detection systems, emitting two wavelengths (“colors”) of electromagnetic radiation from the same aperture is disclosed.
