Problems solved by technology

Therefore these architectures are not suitable for use in any type of in-service, remote or field-deployed portable laser ultrasonic flaw detection system
Additionally, because they are so large and heavy, these architectures require robust robotic grippers and complex beam delivery systems, all of which add significantly to the init

Embodiment Construction

[0031] Preferred embodiments of the invention are depicted in the drawings, like numerals being used to designate like and corresponding parts in the different drawings.

[0032] Laser ultrasonic flaw detection has proven to be a cost-effective tool for non-destructive evaluation (NDE) of polymer-matrix composites. With the increasing use of these composite materials in different industries, the number and complexity of composite parts is increasing. In addition, the installed base of composites is increasing. As objects made of composite materials increase in size and complexity, it becomes increasingly difficult to position laser ultrasonic sensors relative to the surface being inspected. Embodiments of the invention disclosed herein propose a solution to this problem.

[0033] One embodiment places a laser ultrasonic sensor (ie, a laser ultrasonic head) at the end of an articulated robot. Laser ultrasonic flaw detection is typically performed by moving the laser ultrasonic...

Abstract

An ultrasonic non-destructive evaluation (NDE) system operable to inspect target materials is provided. This ultrasonic NDE system includes an articulated robot, an ultrasound inspection head, a processing module, and a control module. The ultrasound inspection head couples to or mounts on the articulated robot. The ultrasound inspection head is operable to deliver a generation laser beam, a detection laser beam, and collect phase modulated light scattered by the target materials. The processing module processes the phase modulated light and produces information about the internal structure ofthe target materials. The control module directs the articulated robot to position the ultrasound inspection head according to a predetermined scan plan.
