Abstract :
An experimental study is made of a two-dimension imaging system using 1-MHz ultrasound, which was suggested in a previous paper as an application of the hologram matrix concerning two orthogonal antenna arrays. Clear image reconstructions are obtained for several targets composed of a set of thin brass rods.
