This study evaluated the impact of water flow on the transmission efficiency of underwater optical wireless power transfer. Using a laser with a wavelength of 532 nm, the optical transmission rate was measured under varying flow velocities (0–8 cm/s) in a controlled water tank environment.
Experimental results revealed a consistent decrease of approximately 3.9% in transmission efficiency with increasing flow velocity. This trend is attributed to enhanced scattering by water molecules as flow velocity rises. Notably, similar reductions in transmission were observed regardless of whether the water flow was in the same or opposite direction to the laser propagation.
