摘要：
THz imaging has turned out to be a very useful technique for applications in nondestructive testing and quality control of industrial objects. Using coherent detection methods amplitude, phase and time information can be obtained. Different properties of objects under investigation can be determined depending on the method of evaluation of the recorded THz signals. These include thickness, shape, density or internal content. Typical examples of THz imaging of industrial objects are presented and the limits of spatial and spectral resolution are discussed.
