摘要： A system is described for emitting a radiofrequency field for a magnetic resonance imaging device, including a volumetric antenna that emits a radiofrequency field, a device for homogenizing the radiofrequency field arranged between said volume antenna and a part of the body to be imaged. The device may include a first continuous metal track with an overall length of approximately 0.5 to approximately 1.5 times said wavelength of the radio frequency field. The first metallic track may occupy a surface with a largest dimension ranging between approximately 5% and approximately 15% of said wavelength of the radio frequency field. The first metal track is arranged in a pattern including a plane of symmetry that is normal to the electrical component of the radio frequency field, so as to give the device an electric dipole property including a natural frequency strictly greater than the frequency of the radio frequency field.

摘要： According to one aspect, the invention relates to a device for transporting and controlling light beams for endo-microscopic imaging without a lens on the distal side comprising a single-mode optical fibre bundle (40) on the distal side, wherein each single-mode optical fibre is intended to receive an elementary light source and to emit a light beam at a distal end; a single-mode optical fibre section (50) arranged at the distal end of the optical fibre bundle and intended to receive the light beams emitted by the single-mode optical fibres of the optical fibre bundle; an optical phase control device arranged on the side of the proximal end of the single-mode optical fibres. The optical phase control device comprises at least one spatial light modulator (30) adapted to apply a phase shift to each of the elementary beams and control means (60) for controlling the spatial light modulator allowing application of a phase shift to each of the elementary beams to form an illumination beam with a determined phase function at the distal end of the multimode optical fibre section (50).

摘要： An attenuation device for attenuating sound waves, and a corresponding system and method, generated by a source emitting sound waves having frequencies between f1 and f2 and wherein the pressure levels are between n1 and n2. The attenuation device comprising at least one acoustic absorber comprising at least one non-linear membrane; the attenuation device being configured in such a way that the first face of the absorber is in acoustic communication with the source. The attenuation device also comprises at least one coupling element for coupling the second face with the source, the coupling element being configured to transmit to the second face sound waves according to the sound waves emitted by the source, and of which the phase and/or the amplitude leads to a pressure differential of the sound waves arriving respectively on the first and second face at the same time.

摘要： According to one aspect, the invention relates to a device (200) for transporting and controlling light beams comprising a light guide (40) comprising a bundle (50) of uncoupled single-mode optical fibers (Fi), each single-mode optical fiber (Fi) being intended to receive an elementary light beam (B1i) at a proximal end and to emit a light beam (B2i) at a distal end, said bundle of single-mode optical fibers comprising, in operation, a minimum radius of curvature corresponding to a maximum curvature of the bundle of fibers. The device (200) furthermore comprises an optical device for phase controlling, said device being arranged on the side of the proximal end of the light guide (40) and comprising at least a first spatial light modulator (30) suitable for applying a phase shift to each of the elementary beams (B1i), and a control unit (60) for controlling the first spatial light modulator, said unit being configured to apply a phase shift to each of the elementary beams (B1i) so as to form, at the distal end of the light guide, an illumination beam with a predefined phase function. According to the present description, said bundle (50) of single-mode optical fibers is twisted, and comprises a twist period (P) defined to preserve said phase function at the distal end of the light guide when the bundle of single-mode optical fibers is subjected to a curvature lower than said maximum curvature.
