Abstract :
We have developed a new millimeter-wave (MMW) imaging system that uses an electrooptic (EO) detector. The EO detector functions as a harmonic mixer for the down-conversion of continuous wave (CW) MMWs. Both amplitude and phase images were simultaneously obtained with this method. Sensitivity, spatial resolution, and imaging of several objects were experimentally shown with MMWs of 60-GHz and 100-GHz frequencies.
