FIELD: instrument engineering.
SUBSTANCE: converter can be used for measuring parameters of acoustic fields in gases and liquids. Fiber-optic converter has optical radiation source exciting circuit, optical radiation source, optical coupler, auxiliary optical radiation, fiber-optic light guide made in form of cylindrical two-channel coaxial tied structure, which has rod single-mode waveguide and tubular single-mode waveguide. Device also has optical radiation divider, which divides optical radiation from rod waveguide and tubular waveguide, optical radiation receiver for receiving optical radiation from output of rod waveguide , additional optical radiation receiver which receives optical radiation from output of tubular waveguide, and analog signal processing unit.
EFFECT: improved precision of fiber-optic converter.
