The detection scheme is sensitive to the material's effect on both the amplitude and the phase of the terahertz radiation. In conservation science used as a nondestructive subsurface analysis of paintings which can reveal buried layer information such as underdrawings or highlight interfaces between layers in a stratigraphic buildup.  ]]></dc:description></metadata>
