Abstract
Terahertz (THz) spectroscopic imaging is an interesting new tool for nondestructive testing and other applications because of good penetration to non-metal material and spectral fingerprints in THz region. However, the current speed of image acquisition is relatively low, making it difficult to use it on moving objects. In this paper, We proposed a fast terahertz color scanner based on electro-optical time-to-space conversion and linefocusing of a terahertz beam. The proposed system functions as a color scanner in the terahertz spectral region with fast line-scanning and can be used to image objects, which are moved on a translation stage. We evaluated basic performance of the developed system.
