An automated laser-based ultrasound system is described that has sufficient sensitivity to detect typical flaws of interest in composite materials without causing surface damage to the part under test. An important step in achieving a rapid scanning

Laminar flow control (LFC) technologies reduce heat-transfer rates as well as the weight and complexity of thermal protection systems (TPS). Previous theoretical and experimental hypersonic wind tunnel studies showed that the laminar run could be sub

State-of-the-art integrally stiffened composite materials, manufactured for use in the next generation of commercial and military aircraft, are increasingly being used for structural components such as wings and fuselages. However, the complexity of

Previously, the applicability of laser-based ultrasonic techniques for the automated inspection of polymer-matrix airframe structures, having either flat or contoured geometries, has been demonstrated without restriction to large radii of curvature.

Current techniques for automated ultrasonic inspection of airframe structures can only be used to examine limited areas which have large radii of curvature. Manual inspection techniques are required in areas having small radii. Laser-based ultrasound

Laser-based ultrasound (LBU) has a number of distinct advantages compared with conventional contact piezoelectric transducer systems. The LBU technique is noncontacting and the laser beams conform to the part surface so that couplant nonuniformities

Using acoustic microscopy, we have examined polycrystalline diamond films grown by theCVD process on silicon substrates. This technique enables nondestructive characterization ofthese films with regard to their grain size, stress patterns and boundar

The conventional Sokolov tube utilizes a piezoelectric plate to convert the incident acoustic signal into an electric signal and also to serve as the interface between the vacuum chamber and the water. This paper describes experiments which use a met
