Preliminary steps to validate a beam model for ultrasonic phased arrays
This paper explores, for various sizes of array and element pitches, the extent to which a beam can be focused, including the effect of failed elements. Experimental data collected with Peak NDT's own array controller has been successfully compared with a computer simulation. This suggests that the computer model can be a useful tool, not only for understanding the ability of a particular array configuration to focus and steer, but also in the development of ultrasonic techniques using phased arrays.
