Optical Beam Attenuation in Atmosphere and Underwater

This training explores the critical concept of optical beam attenuation in both atmospheric and underwater environments, focusing on how environmental factors affect the propagation of optical signals in these mediums. Attenuation is a key challenge in the performance of free-space optical (FSO) communication and underwater optical communication (UWOC) systems. The course covers the physical mechanisms of attenuation, including scattering, absorption, and molecular absorption, and how these factors impact the design and performance of optical communication systems. Participants will gain both theoretical insights and practical skills in calculating and mitigating attenuation effects, with an emphasis on link budgeting, performance optimization, and system design strategies tailored to these challenging environments. Case studies and simulations will be used to showcase real-world applications in both atmospheric and underwater optical communication.
