Review of Progress in Quantitative Nondestructive Evaluation

For a given sample under test, the quality of the ultrasonic image obtained by scanning is greately influenced by the choice of the equipment as well as by the operating conditions. The possibilities of choosing the different parameters is very wide, even if the basic ultrasonic system is determined. The parameters to select before starting an experiment include the transducer itself, its position relative to the sample, the different settings such as gain, attenuation and damping, the mode of detection, etc. The selection is usually dictated by qualitative indications which can be inaccurate or even misleading. Consequently it is very ...
