System and method for terahertz 2D interferometric and synthetic aperture imaging with an incoherent source

摘要

An interferometric and synthetic aperture THz incoherent imaging system is provided, in which a high-power electronic source such as a 0.094 THz Gunn Oscillator is integrated with a continuous-wave (CW) terahertz detection system in order to achieve a high signal-to-noise ratio. THz imaging of a point source located 10 m away from the detector array is presented. A 2-D THz reflective image is reconstructed with only four detectors using rotational synthesis.
