摘要： Ultrasonic scan data is displayed within a display (10) and is arranged in a plurality of two and three-dimensional colored displays (20, 30, 40, 50). A C-scan display (40) is a composite plot of a region of interest using color to designate echo amplitude. The composite plot (40) is time-gated to limit the range of depths of data presented and thereby limit the plot to a tin section such as a surface. Surface breaking discontinuities (100) are visible as highly colored echoes within this C-scan display (40). Within C-scan display (40), once a discontinuity such as a reflector is detected, additional gates (150-165) may be set which permit other specialized displays such as D-scan (50) and B-scan (20) windows to portray the discontinuities. The D-scan plots index direction (54) against time (52), and readily displays circumferential reflectors (130-145) therein, while also enabling rapid estimation of the depth (142) of these reflectors. A B-scan plot (20) which enables fine profiling of reflectors may be a single pane taken at a single axial location determined by an index cursor (168), or may alternatively be a composite plot. Various modifications to the basic system are disclosed that further enhance the utility of the display (10).
摘要翻译：超声波扫描数据被显示在显示器（10）内并且布置在多个二维和三维彩色显示器（20,30,40,50）中。 C扫描显示器（40）是使用颜色指定回波振幅的感兴趣区域的复合图。复合图（40）是时间选择的，以限制呈现的数据的深度范围，从而将图限制到诸如表面的锡部分。表面断裂不连续性（100）在该C-扫描显示（40）内可见为高度彩色的回波。在C扫描显示器（40）内，一旦检测到诸如反射器的不连续性，则可以设置附加的门（150-165），其允许其他专门的显示器，例如D扫描（50）和B扫描（20）窗口描绘不连续性。 D扫描绘制指针方向（54）对时间（52），并且容易地在其中显示圆周反射器（130-145），同时还能够快速估计这些反射器的深度（142）。能够对反射器进行精细分析的B扫描图（20）可以是在由索引光标（168）确定的单个轴向位置拍摄的单个窗格，或者可以是复合图。公开了对基本系统的各种修改，其进一步增强了显示器（10）的效用。

摘要： An ultrasound imaging method forms an image of an object using signals reflected from the object after transmitting an ultrasound pulse to the object. In the method, at a first step, a predetermined first spread spectrum signal is converted to the ultrasound signal at one or more transducers and the ultrasound signal is transmitted to the object. At a second step, pulse compression is performed on a reflected signal of the ultrasound signal reflected from the object to form a pulse compressed signal. And the pulse compressed signal is processed to produce a receive-focused signal and the image of the object from the receive-focused signal is generated.

摘要： A gas sensor includes an element case 42 with an internal peripheral surface formed as a taper surface 100. A portion of a housing section 43 surrounded by the taper surface 100 and a protective film 48 is filled with a filler 49. When the filler 49 thermally expands at high temperature, the filler 49 is subjected to a component of force in an upward direction by the taper surface 100. Therefore, projection of an element portion 44 involving deformation of the protective film 48 is suppressed, a change nullL of a propagation distance L to a reflecting section 33 is also suppressed, and a detection accuracy never decreases. In addition, reverberation is reduced.

摘要： During testing of a panel-like workpiece by means of ultrasonic penetration and at least one inspection channel comprising an ultrasonic transmitter and an ultrasonic receiver on opposite-lying sides of the workpiece, diverse test signals and test information are accumulated at the ultrasonic receiver. Each ultrasonic receiver is connected to an evaluation system, in which the test signals and the test information are combined, evaluated and reduced to a single piece of result-information which describes the tested workpiece. If at least two inspection channels are provided, it can also be provided that a reduction to a single piece of result-information is performed in each case for each ultrasonic receiver.

摘要： A contaminant sensor is provided which has an ultrasonic guided wave transducer that is bonded to a wall in which the ultrasonic energy is transmitted. A detector reflector is provided at a selected distance from the transducer, which will reflect signals that are affected or changed by contaminants collecting on an exposed surface of the wall. A self test reflector is positioned closely adjacent to the transducer and provides a reflected signal that is substantially unaffected by contaminants on the exposed surface of the wall, but which reflects signals only when the transducer assembly is functioning properly, and is properly bonded to the wall. The signal that is reflected by the self test reflector changes when the bond loosens. The receiver is activated right after transmission ceases to determine if the transmitter is operating.
