1. A method for manipulating real-time video playback time-synchronized with millimeter wave imagery, the method comprising: receiving input signals from at least one millimeter wave camera to generate real-time millimeter wave imagery; receiving input signals from at least one video camera to generate real-time visible spectrum video images spatially and temporally relative to the millimeter wave imagery; synchronizing the millimeter wave imagery with the video images to a substantially identical time base; and displaying the millimeter wave imagery and video images in real-time.
