Review of Progress in Quantitative Nondestructive Evaluation

Recently terahertz technology (THz) has emerged as a very powerful NDE tool for inspecting and characterizing dielectric materials. Due to its exceptional longitudinal and lateral resolutions, time-domain pulsed THz scan is particularly effective for inspecting thin layered dielectric media. This pulsed scanning produces multi-dimensional data for which advanced processing techniques are needed to extract and analyze the ample information within. In this presentation we conduct a comparable study of several renowned data processing techniques to determine their applicability and performance in processing THz data. These data processing techniques include an outlier detection algorithm based on minimum covariance determinant estimator, the ...
