摘要: The accurate positioning of an ultrasonic beam (21) to nondestructively test object (11) is achieved by aiming apparatus (10) including transducer (20) generating having a focal point (22) and axis (23), point-source lamp (30) mirror (31) visible light (32) (33) (34). selectively coaxially movable into out coincident at points exterior interior the (11). location may be found aligning coincide alignment spot, moving aligned interest within while maintaining spot.
