Description

Ultrasonic signal analysis and image processing play important roles in the field of NDE. Many methods of ultrasonic imaging such as A-scan, B-scan and C-scan are available. Using such images, NDE tests and analysis can be performed. However, the images are limited by the resolution limits of the imaging system which are established by many factors such as the bandwidth of the transducer, frequency of interrogation, diffraction effects, etc. One of the results of such resolution limits is the blurring of the images.
