In this paper, we propose a new framework of ultrasonic (US) three-dimensional (3D) imaging, introducing laser-induced breakdown (LIB) as an acoustic source. LIB is a phenomenon in which substances transformed to plasma by a pulsed laser beam. LIB explosively emits a variety of energies such as heat, light and sound that also includes pulsed ultrasound. Emitted US waves have suitable characteristics for instantenous US imaging in terms of low directivity to enable a wide view and sharply pulsed waves to enhance the resolution. Utilizing these characteristics, we attempt to apply the synthetic aperture method for frontal 3D imaging in a real-time process. Experimental results show that even sparsely arrayed sensors allow a wider frontal view than that can be achieved in the case using existing transducer devices.
