ABSTRACT:
A device for testing the profile of an ultrasonic beam comprising a block of solid material permitting propagation of said beam therethrough without substantial scattering. A plurality of discrete particles having surfaces interfacing with said solid material are located in and are generally uniformly distributed throughout a substantially planar region in said block. The test device is scanned with an ultrasonic beam and an image of the beam profile is generated by reflection of the beam by the particles.
