Embodiment Construction

[0075] Terahertz imaging systems are mainly divided into terahertz pulse imaging and terahertz continuous wave imaging. The basic principle of terahertz pulse imaging is that the intensity and phase of the terahertz electromagnetic wave reflected from the sample contain the spatial distribution information of the complex permittivity of the sample. The two-dimensional information of the intensity and phase of the reflected terahertz electromagnetic wave is recorded, and the terahertz image of the sample is obtained after proper processing and analysis. The basic principle of terahertz continuous wave imaging is that continuous wave sources provide higher radiation intensity than pulse sources, which is essentially a kind of intensity imaging. When imaging an object, according to the scattering effect of the terahertz light on the edge of the defect or damage inside the object, it will affect the intensity distribution of the terahertz wave electromagnetic field, which is reflecte
