Abstract

Thanks to the development of many kinds of arrays, (mechanical sweeping [1,2], piezoelectric [3,4] or electrostatic [5] transducers arrays), the ultrasonic fields can be sampled with a more and more large apertures and a smaller and smaller sample interval. So the angular spectrum algorithm is becoming perfectly adapted to the field’s numerical reconstruction.
