The power of reflected signal is represented with the height of wave amplitude, it is shown that a kind of " echogram ".M types (spot scan type) are with Vertical Square
The time is represented Xiang representing from shallow to deep locus, horizontal direction, is shown as movement profiles of the luminous point in different time.With
Upper amphitypy is one-dimensional display, is of limited application.Type B (brightness mode) i.e. ultrasound cross-section imaging instrument, referred to as " B ultrasound ".It is
Represent to receive the power of signal with the different luminous point of brightness, when probe is moved along horizontal level, luminous point on display screen also edge
Horizontal direction synchronizing moving, is linked to be the sectional drawing that ultrasonic acoustic beam scanned by luminescent spot track, is two-dimensional imaging.It is root as D types
.C types are made then with the scan mode of approximate TV according to principle of Doppler, show the cross section acoustic image perpendicular to acoustic beam
Figure.In recent years, ultrasonography technology continues to develop, as grayscale show and colour display, real time imaging, ultrasound holography, is worn
Saturating formula ultrasonic imaging, ultrasonoscope and machine tomography rubbish shadow, three-dimensional imaging, ultrasonic imaging etc. in body cavity.
Existing workpiece Non-Destructive Testing is that size or the position of defect are substantially judged by experience mostly, causes the essence of detection
Accuracy is relatively low and can not accurately judge the position of defect, meanwhile, the workpiece that indivedual lossless inside of appearance but damage is not easy to be sent out
It is existing.

Further, the ultrasonic transmitting element transmitting ultrasonic wave, the ultrasonic wave receiving unit reception send super
Sound wave, the ultrasonic signal that the processing unit processes receive, and swept by the scanning element that described control unit controls
Workpiece image is retouched, signal processing unit is acquired signal and is shown by the display unit.
Further, the ultrasonic wave transmitter/receiver unit includes ultrasonic wave transmitting/receiving circuit and amplifying circuit,
The ultrasound wave transmitting circuit transmitting high-voltage pulse, the excitation ultrasound ripple after amplifying circuit, the ultrasonic wave receiving unit connect
Receive echo-signal and the signal processing unit is sent to after enhanced processing.
Further, the scanning element includes the lens and light beam deflection film once connected.Further, it is described aobvious
Show that unit is shown by LED and/or LCD display.The ultrasonic transmitting element uses the model transmitter of T186UE.
The advantage of the invention is that：Ultrasonic wave is launched by ultrasonic transmitting element, ultrasonic wave receiving unit is received and sent
Ultrasonic wave, by described control unit control the scanning element scan workpiece image, signal processing unit to signal carry out
Gather and shown by the display unit.It can accurately judge whether workpiece has damage, and can accurately grasp and damage work
The specific damage position of part, reduces substantial amounts of manpower and materials, while adds the accuracy of detection.
