ABSTRACT:
Described is an anomaly detector apparatus10for detecting an anomaly in a substrate, e.g., a tire comprising: a source of coherent light20to shine the light27directly onto the tire surface24and the light being reflected32from the tire; a stressing apparatus12, which is juxtaposed to the tire and which, can optionally stress the tire; a reflected light receiving apparatus40for receiving the light32reflected directly from the tire surface24whether the tire is in a stressed or unstressed condition; a comparator44which views and compares images of reflected light from the reflected light receiving apparatus40when the tire is stressed or unstressed thereby ascertaining an anomaly in the tire and generates an output from the comparison; and a display apparatus46electronically connected to the comparator for displaying the output from the comparator. Also described is a plurality of sources100and light receiving apparatus102sitting atop a vertically moving support structure110that may view 360 degrees, of the whole circumferential interior surface of the tire.
