摘要： A method for determining an acoustic power of an ultrasonic emitter comprises coupling the ultrasonic emitter to a test medium, driving the ultrasonic emitter to induce acoustic waves in the test medium along an acoustic wave propagation direction, the acoustic waves causing a change of the refractive index of the test medium, selectively irradiating a probe portion of the test medium with a collimated beam of light along a beam direction which is different from the acoustic wave propagation direction, such that the collimated beam of light intersects the acoustic waves, passing the collimated beam of light through an optical element or optical assembly configured for focusing the collimated beam in a focal plane, and determining the acoustic power of the ultrasonic emitter based on a refraction-induced width of a light intensity distribution in the focal plane.

摘要： An ultrasonic imaging system incorporates an imaging device utilizing confocal acoustic focusing of ultrasonic transducers together with apparatus for moving points of focus of the transducers to scan a volume to be imaged and gather data as to the acoustic reflectivity of matter within the volume, the gathered data being used to construct an image of the volume. In a preferred arrangement the point of focus of each transducer is moved in three dimensions. Use of confocal techniques can permit enhanced resolution to be obtained compared with conventional ultrasonic imaging techniques. In a preferred arrangement, the confocal focusing system associated with each transducer includes a pinhole which is bridged by an acoustically transparent but optically reflective diaphragm, and acoustic reflectivity data is recovered by interrogating each diaphragm by means of an optical interferometer. Optical signals from the interferometer may be scanned over an array of optical sensors such as a charge coupled device array to segment and temporarily store the optical data.
