UNDERWATER OPTICAL COMMUNICATION APPARATUS Russian patent published in 2014 - IPC H04B10/00 

FIELD: physics, communications.

SUBSTANCE: invention relates to electrical communication engineering and can be used in two-way optical communication systems. An underwater wireless optical communication apparatus, having an optical receiver and a transmitter with control circuits therefor, further includes a rotating device, a position-sensitive element and a master controller, wherein all optical subsystems are rigidly joined to each other, are mounted on the rotating device and angle apertures thereof are linked by the relationship θ_t<θ_R<θ_p, where θ_t is the angle of divergence of the radiation of the transmitter; θ_R is the angular field of view of the receiver; θ_p is the angular field of view of the position-sensitive element.

EFFECT: broader functional capabilities of the apparatus for two-way optical communication in an underwater environment.
