FIG. 8.

(Color online) Measured and simulated 2D pressure amplitude distributions recorded in the transverse focal plane of the array. The distributions are collected in free field and in the same plane with phantoms inserted in the propagation path. Pressures in all plots are normalized to the maximum value in each individual plot. (a) Free field experiment; (b) free field simulation; (c) wedge phantom experiment; (d) wedge phantom simulation; (e) aberrating phantom experiment; (f) aberrating phantom simulation.
