The plurality of n lasers can simultaneously illuminate the beam splitter along a coincident axis. The plurality of n lasers can be selectively blocked so that only one laser wavelength λi at a time impinges on the beam splitter. A portion passes through the beam splitter to establish a reference signal, while the remainder is reflected off the corner retro-reflector. A portion of return illumination passes through the beam splitter to establish a return signal. The process can be repeated for each of n lasers for i=1 to n. The λi wavelength where the normalized signal-to-noise differential between the reference signal and return signal is the minimum can be the optimum communication wavelength."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wavelength optimization for underwater optical communications","description":"Systems and methods for wavelength optimization for underwater optical communication can include a plurality of n lasers having different wavelengths λi for i=1 to n, a beam splitter and a corner retr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9647771","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.
