A Review of Nonlinear Ultrasonic Array Imaging

Jack Potter

Research output: Contribution to journalReview article (Academic Journal)


This paper presents a review of techniques for the imaging of elastic nonlinearity using ultrasonic phased arrays. Such methods are
applied within the field of nondestructive testing of materials, most notably in application to the imaging of tightly closed cracks. The
methods of nonlinear imaging are grouped into three distinct classes. The underlying principles of each class are detailed and key
experimental imaging results reported.
