Development of Advanced NDE Ultrasonic Equipment
Recent studies to determine the probability of detection of nondestructive exami r.ati on methods by the Air Force indicate that these capabilities are severely limited. One of the factors contributing to the insufficiency of ultrasonic testing is related to a general lack of versatility and capability of commercial ultrasonic equipment. Inadequate instrument reliability, inconsistent component...
متن کامل[The development of ultrasonic diagnostic equipment for dental use].
When a dentist prepares a vital tooth, it is very important to know the distance between the prepared surface and the pulp chamber wall, and now we have developed ultrasonic diagnostic equipment which can indicate the nearness of these two boundaries by measuring the thickness of the remaining dentin. This equipment can be used to measure the thickness of the remaining dentin between the prepar...
متن کاملAudibility of Complex Tones above 20 Khz
Audibility of ultrasonic components contained in a harmonic complex tone were investigated. The level of the components varied adaptively and the maximum level investigated was 80 dB SPL / component. All subjects distinguished between sounds with and without ultrasounds only when the stimulus was presented through a single loudspeaker. When the stimulus was divided into six bands of frequencies...
متن کامل3D-SAFT Ultrasonic Inspection Equipment “MatrixeyeTM”
3D ultrasonic inspection equipment “Matrixeye” can visualize defects as 3D image with good resolution by the 3D SAFT (Synthetic Aperture Focusing Technique) imaging method. High-speed 3D SAFT imaging process can be achieved by the developed parallel signal process of the ultrasonic echo data collected by a linear or a matrix-array ultrasonic probe. It has the following features. •3D image with ...
