Defect Assessment Using Conformable Array Data
ABSTRACT
The conformable array data acquisition system consists of the array, the data acquisition and analysis hardware, and the
data acquisition and analysis software. The following decisions were made in the development of the system. Array design
decisions include the following: (a) The flexible array board will be approximately 8 by 12 inches square with the active coil
section confined to a smaller 6-inch-square section at the center of the board. The outer edges of the board will be used for
switching and other circuitry. (b) The diameter of the array coils will be approximately 0.375 inch (9.5 mm). Software
decisions consisted of selecting the appropriate LABVIEW modules running in a Windows XP operating system to obtain the
required functionality. This third quarterly report of the project presents the activity and conclusions reached to date.
Specifically, the design of the conformable array was completed and work was started on obtaining the data acquisition
hardware. Southwest Research Institute (SwRI) and Clock Spring staff met at the SwRI facilities in June 2003 to discuss
the project. The Clock Spring representative was given the latest version of the data acquisition and analysis software for
evaluation. Comments were received.
