Abstract

PURPOSE: To make possible ultrasonic flaw detection at a high speed irrespective of temperatures such as high temperatures by scanning and radiating the surface of the object to be examined with the rotary mirrors make a pair to a plurality of half mirrors thereby inducing ultrasonic waves in the object to be examined.
CONSTITUTION: laser light from a laser source L transmits through half mirrors H1, H2... and at the same time, part thereof reflects thereon and is then reflected by the rotary mirrors R1, R2... which make a pair with the mirrors H1, H2... and scans and radiates the surface of a steel product or the like M under production moving at a higher speed at a high temperature over its entire width. Ultrasonic waves are generated in the steel product or the like M by the impact owing to this radiation and propagate in the steel product or the like M. The ultrasonic waves are then detected with ultrasonic wave detecting elements P..., thus the ultrasonic flaw detection of the steel product or the like M is accomplished noncontactually without intervention of any medium or the like. Hence, the accurate ultrasonic flaw detection may be accomplished at a high speed irrespective of temperatures.
