Paper Abstract

Terahertz radiation is a special electromagnetic spectrum range sandwiched between the infrared ray and microwave. With developing of super fast and super power laser technology, this special range has been explored extensively. Among all terahertz technologies, terahertz imaging may be the first one can be used in the practical applications. In this presentation, a novel terahertz multi-spectral focal plane imaging method is proposed. Using a CCD camera instead of the single detector, this method can capture the time domain waveform of an object quickly. Using the fast Fourier transform, both the amplitude and phase of the THz spectrum can be achieved. Based on this information, the layer structure inside the object can be presented. The multi-spectral phase imaging technology has also been employed to get high signal noise ration.
