Terahertz (THz) radiation can penetrate nonmetallic materials and nonpolar materials, and has low photon energy, therefore THz imaging has drawn more attention. The moment function of an image has wide applications on pattern recognition and target classification. The paper has applied image segmentation to Continuous-Wave THz point-to-point scanning reflecting image depending on Otsu's method. The...
THz laser can penetrate a wide range of materials which are opaque to visible and near infrared light. So THz imaging has been an important research direction nowadays. When using the THz imaging methods of point-by-point scanning transmission, the laser output power’s fluctuation has a big influence on the imaging quality, which is the main source of the imaging noise. In this paper, the influence...
