Abstract
The fiber optic probe detects changes in ultrasound pressure in an immersion medium such as a liquid, a gas, or a solid, where the system includes an optical fiber probe having a fiber of the probe has a highly doped (or regular) core with a diameter in the range 5 to 10 μm and a clad diameter equal to or more than 50 μm; and the optical fiber tip has been modified in a D-shaped (or V-shaped) structure where the clad material has been removed from one side of the cylindrical fiber to the surface of the fiber core; then, this modified region of the fiber is coated, with a very thin layer of a metallic material, ranging from 3 to 10 nm.
