TL;DR: An efficient all-fiber optic source is presented; it adopts absorbing films, deposed directly over the fiber tip, as targets, and it is observed that the conversion efficiency increases monotonically as thickness is reduced down to the material optical penetration depth.

TL;DR: 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 impinged upon by the laser beam and to absorb partially the energy, converting it into thermal energy, thus bringing about the formation of ultrasound wave by the thermoacoustic effect as mentioned in this paper.

TL;DR: The architecture of a hardware and software platform, used in conjunction with an analog front-end hardware for driving the ultrasonic transducers of any commercial echograph, having the radiofrequency echo signal access, make it possible to dispose of a powerful echographic system for experimenting any processing technique, in a clinical environment in which real-time operation mode is an essential prerequisite.

TL;DR: In this paper, an innovative photoacoustic source for ultrasonic non destructive evaluation (NDE) and clinical diagnosis is proposed based on thermal conversion of laser pulses into a metallic film evaporated directly onto the tip of an optical fiber.

TL;DR: An acoustic dynamic characterization of UCA microbubble behavior was performed using a high frame-rate acquiring and processing system and several sequences of RF echo signals and the related spectra, acquired from an isolated bubble in different insonation conditions, are presented.
