Polymer optical fibre (POF) presents a novel approach for endoscopic applications and has been positively discussed and compared in existing publications. A great advantage can be obtained for endoscopy due to a small size and array potential to provide discrete imaging speed improvements.

The opto-acoustic generator of ultrasound waves comprises an optical fiber associated to a laser-energy source, and an opto-acoustic transducer which is applied to said fiber and is designed to be

The fiber of the sensing arm was wrapped onto a thin foil arranged close to the cylindrical walls of the acoustic cell. Thus the acoustical waves generated by the absorbed light were transferred to an elongation of the fiber. The cell was operated at one of its resonances. 2011-09-26 Opto-Acoustic Fiber Sensor Opto-Acoustic Fiber Sensor Munir, Q.; Weber, H.

According to the World Health Organization (WHO, Geneva, Switzerland; www.who.int) over half a million women died in 2015 due to breast cancer.Although breast cancer can be discovered when symptoms may appear, many women will have no symptoms, making … Optoacoustics | Fiber Optic Microphones and Sensors. 2011-09-26 · 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. Abstract. 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.

Similarly, opto-acoustic sensing and transmission system 40 is connected to tank 12.

United States: N. p., Fiber delivered laser pulses emulsify thrombus by mechanical stresses that include a combination of pressure, The opto-acoustic system 30 receives optical power through fiber optic cable 36 from optical power source 38. Similarly, opto-acoustic sensing and transmission system 40 is connected to tank 12. The intrinsic high frequency and wide bandwidth associated both to the opto-acoustic source and to the interferometric acousto-optic element could open a way towards a “virtual biopsy”. “Virtual biopsy” is perspective to provide the physicians the possibility of studying the nature and health condition of small portions of living tissue “in situ” by using ultrasounds.
