Abstract
A light weight hand held ultrasonic scanner for ultrasonic flaw detection systems utilizes an omnidirectional rolling ball element which drive optical encoders for X-Y coordinate position location of flaws. The rolling ball element is mounted in a body for rolling contact with a surface to be inspected. An ultrasonic transducer is mounted at one end of a second hollow body attached to the first body. An ultrasound reflector is provided in the hollow body to reflect an ultrasound beam transversely out of the second body.
