摘要： The present invention relates to a method and apparatus for focusing ultrasonic waves that are propagated from a phased array toward a spherically-bounded object so that they arrive at a pre-selected focal point at the same time and in phase and thereby significantly improve, nondestructively, the detectability of possible flaws in and structural characteristics of the object. The disclosed method comprises calculating the location of a plurality of preferred refraction points on a surface of the spherical work piece using an iterative process. Each of the preferred refraction points correspond to one of the elements of the phased array mechanism. The locations of the preferred refraction points depends upon the location of the pre-selected focal point and the locations of the phase elements. After the preferred refraction points are calculated, the method comprises calculating a pulse firing time for each element of the phased array mechanism that relates to the relative timing of the emitted waves from the elements.

摘要： In view of the fact that, when backup roll bearings which have been found satisfactory in the purity thereof in the sample evaluation through observations using a microscope are checked many times for the top surface layer portions of the raceway surfaces thereof according to an ultrasonic detecting method, on quite rare occasions, there can be found a bearing which contains one or more inclusions each having a size of as large as several hundreds &mgr;m, and such inclusions give rise to occurrence of a short-life bearing as a finished product, a range expressed by 2% Da depth×raceway surface is used as a test piece volume and the size of a non-metallic inclusion existing in the test piece volume is restricted to a length less than 500 &mgr;m, preferably, less than 100 &mgr;m. Here, the term “2% Da depth” means a depth up to 2% of a rolling element mean diameter from the surface of an inner or outer race of a bearing.

摘要： An ultrasonic imaging system including an aberration correction system uses a harmonic component of the fundamental transmitted frequency for imaging, or for aberration correction, or both. By properly selecting the frequency pass bands of filters used in the image signal path and in the aberration correction signal path operating advantages are provided. The aberration correction values may be calculated concurrently with image formation.

摘要： In a method for ultrasonic testing of objects, ultrasound is generated inside or at the surface of the object. The surface of the object is illuminated with a beam from a long-pulse laser oscillator, typically in the range 1 &mgr;s to a few 100 &mgr;s, that is substantially free of intensity fluctuations. The light from the incident beam that is scattered or reflected by the surface of the object is collected and demodulated to obtain a signal representative of the ultrasonic motion. The method allows for the use of a compact and efficient arrangement.

摘要： A palm-held acoustical sensing device provides improved accessibility within an engine compartment for sensing engine noise in order to perform diagnostics. Miniaturized electronics are provided within a compact housing that permits free use of the sensing device within an engine compartment, enabling access to engine components that have previously been accessible only with great difficulty. Clamping sensors having wider bandwidth than existing clamping sensors provide improved sensing capability and an electronics and battery housing having one or more sensor input jacks provides for attachment of multiple sensors, improved storage and a lower cost unit providing the advantages of both a flexible shaft sensing unit and a clamping unit.
