Abstract
Operating parameters are selected for inspecting a structure. Selecting the operating parameters includes exciting broadband ultrasonic guided waves in a multilayered structure, acquiring data corresponding to the sensed broadband ultrasonic guided waves in the multilayered structure, selecting one or more narrow frequency bands based on the acquired data, and inspecting the multilayered structure using ultrasonic guided waves in the one or more narrow frequency bands. In some examples, the data is acquired by an inspection tool capable of sensing the broadband ultrasonic guided waves in the multilayered structure.
Claims20
A method of selecting operating parameters for inspecting a structure, the method comprising:
- exciting broadband ultrasonic guided waves in a multilayered structure;
- acquiring, by an inspection tool capable of sensing the broadband ultrasonic guided waves in the multilayered structure, data corresponding to the sensed broadband ultrasonic guided waves in the multilayered structure;
- selecting one or more narrow frequency bands based on the acquired data;
- and
- inspecting the multilayered structure using ultrasonic guided waves in the one or more narrow frequency bands.
A system of selecting operating parameters for inspecting a structure, the system comprising:
- an ultrasonic transmitter configured to excite broadband ultrasonic guided waves in a multilayered structure;
- an ultrasonic receiver configured to sense the broadband ultrasonic guided waves in the multilayered structure and to generate data corresponding to the sensed broadband ultrasonic guided waves in the multilayered structure;
- and
- a controller configured to select, based on the acquired data, a narrow frequency bandwidth of ultrasonic guided waves for use in a subsequent inspection of the multilayered structure.
A computer-readable storage medium having embodied thereon instructions for selecting operating parameters for inspecting a structure, wherein the instructions, in response to execution by a computing device, cause the computing device to:
- excite broadband ultrasonic guided waves in a multilayered structure;
- acquire, from an inspection tool capable of sensing the broadband ultrasonic guided waves in the multilayered structure, data corresponding to the sensed broadband ultrasonic guided waves in the multilayered structure;
- select one or more narrow frequency bands based on the acquired data;
- and
- inspect the multilayered structure using ultrasonic guided waves in the one or more narrow frequency bands.
