ABSTRACT:
Described is an anomaly detector apparatus10for detecting an anomaly in a tire comprising: a source of coherent light18to shine the light27directly onto the tire surface24and the light being reflected32from the tire; a stressing apparatus12which can stress the tire; a reflected light receiving apparatus40for receiving the light32reflected directly from the tire surface24when the tire is in a stressed and unstressed condition; a processor44which compares images of reflected light from the reflected light receiving apparatus40when the tire is stressed and unstressed thereby ascertaining an anomaly in the tire and generates an output from the comparison; and a display apparatus46electronically connected to the processor for displaying the output from the processor.
