  • Abstract
    Recent years have seen rapid increase in 2 Dimensional arrays for NDE imaging applications. This paper applies conformal mapping techniques as a means of designing non-periodic, sparse array transducers. Extensive field modeling using Huygens´ principle is employed to study merits of the new array layout. Finally, an image processing methodology to conveniently compare various aperiodic designs is presented.
