This invention is an optically activated transducer for generating acoustic vibrations in a biological medium. The transducer is located at the end of a fiber optic which may be located within a In this research, time-resolving opto-acoustic fiber sensor for registration of acousto-optical signal parameters in devices with fiber-optic delivery systems of pulsed laser radiation and feedback systems has been advanced and investigated for the first time. An opto-acoustic hydrophone converting acoustic signals to corresponding modulated optical signals and transmitting the converted signals via a fiber optics cable to a sonobuoy. Light reflected from a mirror or equivalent oscillating in accordance to received acoustic signals is transmitted via fiber optics to a sonobuoy for further transmission.

Massimo Moccia In this paper, we present the study of the acousto-optic behavior of underwater-acoustic sensors constituted by fiber Bragg gratings (FBGs) coated by ring-shaped overlays. Via full-wave numerical simulations, we study the complex opto-acousto-mechanical interaction among an incident acoustic wave traveling in water, the optical fiber surrounded by the ring shaped coating, and the FBG inscribed An acousto-optic modulator, also called a Bragg cell or an acousto-optic deflector, uses the acousto-optic effect to diffract and shift the frequency of light using sound waves. They are used in lasers for Q-switching, telecommunications for signal modulation, and in spectroscopy for frequency control. A piezoelectric transducer is attached to a material such as glass. An oscillating electric signal drives … More specifically, we study the complex opto-acousto-mechanical interaction among an incident acoustic wave traveling in water, the optical fiber surrounded by the ring-shaped coating, and the FBG inscribed in the fiber, via full-wave numerical simulations by means of a multiphysics software package based on the finite-element method (FEM). Scientists at EPFL, Switzerland, develop opto-acoustic method to identify fiber’s surroundings. Sensitive: Desmond Chow, co-author of the EPFL study.

An optoacoustic sensor for trace analysis in gases was constructed and experimentally tested. The crucial element in such systems, the highly sensitive electronic microphone, was replaced by a fiberoptic interferometer in the Mach-Zehnder configuration. Via full- -wave numerical simulations, we study the complex opto-acousto-mechanical interaction among an incident acoustic wave traveling in water, the optical fiber surrounded by the ring shaped coating, and the FBG inscribed the fiber, focusing on the frequency range 0.5-30 kHz of interest for SONAR applications. The fiber optic acoustic sensors, which are operated in interferometric techniques [7] and fiber grating techniques [8], can be applied to separately quantify the power density and the frequency Opto-acoustic Coupling and Brillouin Phenomena in Microstructure Optical FibersHervé Maillotte (1) , Jean-Charles Beugnot (1) , Birgit Stiller (1) , Min Won Lee (1) , Duc Minh Nguyen (1) , Michael Delqué (1) , Sarah Benchabane (2) , Vincent Laude (2) , Stella Foaleng Mafang (3) , Luc Thévenaz (3) , Géraud Bouwmans (4) , Alexandre Kudlinski (4) , Gilles Mélin (5) , Jérôme Hauden (6 Opto-acoustic behavior of coated fiber Bragg gratings.
