| Abstract | Application of terahertz (THz) electromagnetic waves offers several opportunities for quality inspection in various industries. The THz waves penetrate many kinds of materials such as pharmaceutical coating, paper, plastic, ceramic, cardboard, wood, clothing, etc. We investigated possibilities of applying a THz imaging system in transmission geometry using the organic DSTMS crystals as a THz generator and detector. We applied different methods to construct an image from the array of THz pulses. Time-domain THz imaging has the advantage of the fast sample scanning. It is however appropriate only for detection of imperfections or impurities inside the material as well as for the thickness distribution measurement. For identification of the observed substance multispectral imaging is necessary. |
