Terahertz imaging is a scanning technique that uses terahertz frequency waves from 0.3 to 10 THz to penetrate through dense objects. Owing to its comparatively low photon energy, terahertz radiation does not cause any changes in the chemical structure unlike x-rays and UV radiation. Also, it does not harm the human body and the other objects it passes through, due to its non-ionizing and modest operating frequency range. Therefore, it is expected to be one of the significant nondestructive evaluation technique for quality control and material analysis in different industries including aerospace, pharmaceutical, security, and biomedical among others. The key factor driving the growth of the terahertz imaging market include the increasing demand for security systems across the world. As terahertz imaging systems use terahertz electromagnetic waves that have low photon energy, they are environment-friendly and harmless when one is exposed to them. Governments are introducing stringent reg...
