LABORATORY INVESTIGATION OF NON-LINE-OF-SIGHT OPTICAL COMMUNICATION AT 450 AND 850 NM WAVELENGTHS IN TURBID MEDIA
Abstract and keywords
Abstract:
Recently, there has been growing interest worldwide in the development of high-speed optical communication non-line-of-sight (NLOS) systems. The primary advantage of optical NLOS communication systems is the ability to transmit data despite obstacles in the line of sight, as well as the potential for multi-address and interference-resistant communication. This study evaluates the effect of a water-glycerol aerosol on optical communication at wavelengths of 450 nm and 850 nm over a baseline distance of 19 m. The results demonstrate that in a clear atmospheric environment, communication at λ = 450 nm is unstable, whereas at λ = 850 nm, no link is established. However, in the presence of a turbid medium within the test chamber, error-free communication becomes achievable.
