Abstract:

The objectives of the reported work were 1 to assess the status of optical techniques for nondestructive evaluation and 2 to relate available optical phenomena and methods to nondestructive inspection problems. The intended reader benefits of this technology assessment of optical methods for nondestructive evaluation are twofold. First, brief, qualitative descriptions of selected optical methods which may be useful in nondestructive evaluation applications are given to help the reader quickly understand the principles involved and to visualize typical apparatus configurations. Second, specific examples of applications of optical techniques to nondestructive evaluation problems as reported in the literature are discussed so that the reader can readily grasp the variety of nondestructive evaluation problems to which the selected optical technologies can be applied. These descriptions of specific applications are in sufficient detail that the reader can determine whether or not a particular optical method is applicable to a nondestructive evaluation problem which he faces. Additionally, descriptions of apparatus and procedures and numerical data concerning accuracies, resolutions, operating ranges, and other pertinent factors are included so that the reader can further assess applicability of a particular method to his problem and so that he can weigh possible benefits against process complexity, apparatus cost, etc. Author
