    Abstract: A passive millimeter-wave imaging system configured as an integrated circuit. The imaging system incorporates a lens which focuses radiation from a scene onto a detector in the focal plane of the lens. The detector includes an outer array of ferroelectric elements in which each element includes a top metal film and a ferroelectric layer. Millimeter-wave radiation from the beam causes charge build-up in the ferroelectric layers. The charge build-up is sensed by appropriate amplification and signal processing circuitry associated with the read-out electronics so as to provide a signal indicative of obstacles in the scene to a video system. The ferroelectric layer can also be used as an antenna for each pixel element.
