Urgent issues of detecting objects made of polymer materials using 3D printing technology
There is need for application noted as part of technical devices physical protection objects systems providing item detection in article. They are made of polymeric materials using 3D printing technology. For these purposes, inspection complexes can be used whose operation is based on radio - wave imaging in the terahertz (sub - terahertz) frequency range. Based on the analysis of such complexes, the article proposes their conditional classification according to the following features: frequency range used, type of scanning radiation source, type of execution. The developed classification allows a comparative analysis of existing search systems, to identify their advantages and disadvantages. In addition, suggestions have been formed on the use of these complexes as part of physical protection objects systems.
