We have demonstrated video-rate millimeter-wave (MMW) shadowgraphy using a slab of the positive column of Cs–Xe dc discharge as a two-dimensional real-time MMW sensor. MMW images were converted into visible images using the visible continuum from the plasma slab. Near-field shadow projection MMW images of amplitude and phase objects have been obtained using pulsed watt-scale 35.4 GHz radiation for object illumination. The single-frame signal-to-noise ratio was about 13 dB for an exposure time of 1 ms. Time-averaged MMW intensity could be about several in the case of video-rate imaging.
