Field correlations of partially coherent optical beams in underwater turbulence

Field correlations of partially coherent optical beams at the receiver plane are formulated and evaluated in underwater turbulence. Variations of the field correlations are examined against changes in the degree of source coherence, diagonal length from the receiver point, receiver point, propagation distance, source size, ratio of temperature to salinity contributions to the refractive index spectrum, rate of dissipation of mean-squared temperature, and rate of dissipation of kinetic energy per unit mass of fluid. Under any underwater turbulence and link conditions, it is found that field correlations at the receiver plane reduce when the optical source becomes less coherent. (c) 2022 Optica Publishing Group

Automated summary

Field correlations of partially coherent optical beams in underwater turbulence are studied in this paper. The variations of field correlations with changes in the degree of source coherence, receiver point position, propagation distance, and other factors are examined, and it is found that reducing the source coherence leads to a decrease in the field correlations at the receiver plane.
