Paper Abstract

An engineering prototype of underwater wireless optical static monolithic communication system based on blue LED with high power and large field of view as communication light source and APD with high sensitivity and large target surface as receiving unit is established. The prototype adopts OOOK modulation mode, uses Fresnel lens with diameter of 75 mm and focal length of 25 mm as optical receiving antenna, installs narrowband filter, reduces signal-to-noise ratio, carries out communication coding through FPGA, and adopts staring direct detection mode to realize engineering integration of underwater wireless optical communication technology system, and intends to establish communication distance. The underwater large-field-of-view wireless optical communication link with a communication rate of 10 Mbit/s and a distance of 20 m. The performance parameters such as communication distance, power attenuation, communication delay, water disturbance and channel scattering of the system engineering prototype are measured and analyzed.
