Process and apparatus for testing of rails by ultrasound |
摘要 |
Beams of ultrasound are transmitted into a rail. The transmission alternates between vertical and oblique beams. Transmission of the beams and reception of ultrasonic echoes is accomplished by a probe which includes a two channel ultrasonic transducer. The echoes are displayed simultaneously on two linear arrays of LED's which are arranged to resemble the relationship between a vertical beam and an oblique beam.
