Combining opto-acoustic imaging with conventional ultrasound techniques allows radiologists to more accurately classify breast tumors. According to the World Health Organization (WHO, Geneva, Switzerland; www.who.int) over half a million women died in 2015 due to breast cancer. Knowledge in Fiber Bragg Gratings or any kind of opto-acoustic sensors is an advantage. A strong desire to work at the leading edge of materials technology and a high level of motivation to work in an international, multidisciplinary research team in the field of laser physics, material scientist and data scientist are essential. opto-acoustic and aeousto-optic conversion lets us fore- see the possibility of realizing complete miniaturized transmitting-receiving transducers, able to generate and de- tect wideband ultrasounds by laser light. In the present pa- per, a miniaturized ultrasonic transducer entirely based on fiber optic technology is proposed. An ultrasonic probe was developed by using, in conjunction, optoacoustic and acousto-optic devices based on fiber optic technology.

An opto-electronic oscillator based on guided acoustic wave Brillouin scattering in a photonic crystal fiber (PCF) stimulated by a light wave in 1 μm band is proposed and demonstrated. A short length of a homemade PCF stimulated by relatively low pump power leads to strong coupling between the pump and probe waves.

INTRODUCTION . Opto-acoustic imaging is a growing field of research in recent years, providing functional imaging of physiological parameters such as haemoglobin concentration. Opto-acoustic thrombolysis. 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.

1. INTRODUCTION . Opto-acoustic imaging is a growing field of research in recent years, providing functional imaging of physiological parameters such as haemoglobin concentration. Opto-Acoustic Endoscopy (OAE) requires sensors with a high sensitivity and small physical dimensions in order to facilitate integration into an endoscope of less than 1mm in diameter.

Thus the acoustical waves generated by the absorbed light were transferred to an elongation of the fiber.
