摘要： An acoustic microscope for analyzing an object in depth has aspherical lenses. It comprises two identical bars arranged in the extension of one another and provided on their facing ends with a cavity, said cavities defining a pseudo-hyperbolic focussing lens and objective lens, whereby the foci of said two lenses coincide and the lenses are linked by a mercury or gallium drop in which can be immersed the object to be analyzed. The bars are provided at their other ends with a piezoelectric transducer. These transducers are able to produce ultrasonics focussed within the object by the focussing lens and are able to detect the ultrasonics reflected or transmitted by the object via the objective lens. These are also means for analyzing ultrasonics reflected or transmitted by the object and means for displacing the object in the focal plane of the two lenses.

摘要： A device measures the propagation time for an acoustic wave in a continuous phase of a two-phase mix (28) comprising the continuous phase and a dispersed phase forming droplets (40) in the continuous phase. The device comprises an electro-acoustic transducer (12) capable of emitting acoustic waves (30) and outputting a reception signal of reflected acoustic waves, a signal pulse generator capable of determining a propagation time starting from signals output by the transducer, and an acoustic lens for focusing acoustic waves and the frequency of the acoustic waves being adjusted to cause reflection of the waves on the droplets of the dispersed phase, essentially located within a focusing area.

摘要： The present invention relates to a micro-echographic probe for ultrasound collimation through a deformable surface. The probe comprises at one end an ultrasonic wave beam transducer, disposed, for example, in the form of a spherical cap, so that said beam converges in a focus (A), which focus is also that of the other end of the monolithic body and which is the contact tip, so that the beam which penetrates in the body to be analyzed is collimated. The ultrasonic waves are preferably at a frequency equal to at least 50 MHz.
