The effects of air gap reflections during air-coupled leaky Lamb wave inspection of thin plates.

Air-coupled ultrasonic inspection using leaky Lamb waves offers attractive possibilities for non-contact testing of plate materials and structures. A common method uses an air-coupled pitch-catch configuration, which comprises a transmitter and a receiver positioned at oblique angles to a thin plate. It is well known that the angle of incidence of the ultrasonic bulk wave in the air can be used...

Ultrasonic Lamb wave tomography

Nondestructive evaluation (NDE) of aerospace structures using traditional methods is a complex, time-consuming process critical to maintaining mission readiness and flight safety. Limited access to corrosion-prone structure and the restricted applicability of available NDE techniques for the detection of hidden corrosion or other damage often compound the challenge. In this paper we discuss our...

Laser-air Hybrid Ultrasonic Technique for Dynamic Railroad Inspection Applications

Laser-Air Hybrid Ultrasonic Technique (LAHUT) combines laser generation with air-coupled detection of ultrasound. The technique is non-contact and has the characteristic of operating from remote distances. Acoustic wave laser-generation apparatus can be meters away from the interrogated surface while air-coupled detection standoff can be on the order of several centimeters. The technique has th...

Air Coupled Ultrasonic Inspection of Steel Rubber Interface

This paper describes the investigation for the feasibility of inspection of steel-rocasin rubber specimen used in rocket motor for detection of debond by using air-coupled ultrasonic. A pair of high performance air-coupled transducers was used to generate and receive the high intensity ultrasonic pulses. Probes were placed at the opposite side of the specimen during inspection. It was shown tha...

Dynamic railroad inspection using the laser-air hybrid ultrasonic technique

In recent years, remote non-contact NDE techniques have been sought in an effort to improve railroad related inspection operations. More specifically, efforts have been aimed at increasing the inspection coverage and performing dynamic inspections for railroad tracks and wheels. Throughout most of the 20th century, dynamic inspections of railroad tracks have been developed and performed, howeve...
