NON-DESTRUCTIVE TESTING APPARATUS AND METHOD

摘要

A non-destructive testing apparatus according to the present invention includes a detector, a display unit and a processor. The detector measures a test object to generate a measurement signal in a first coordinate system. The processor maps the measurement signal in the first coordinate system onto a second coordinate system to produce a second coordinate system measurement signal, removes a noise component from the second coordinate system measurement signal to produce a resultant signal, and controls the display unit to display the resultant signal. The processor may also attenuate a part of the noise component using a variety of filters. An apparatus according to the present invention, and a method therefor, may be used in order to test components within a system which may undergo influences such as vibration and heat change, therefore being susceptible to flaws or damages.
