Patent ID: 8263939

Claim:
A millimeter wave imaging apparatus comprising: a mirror array having a plurality of electronically tunable impedance surface mirrors, wherein the plurality of mirrors is capable of receiving a millimeter wave signal, the array comprising a number of diodes disposed such that a change in impedance of a diode directs a millimeter wave signal received at a mirror to a desired direction; the mirror array further comprising a polymer microtruss, a substrate, a bias board, a number of connectors, and a number of patches connected to the diodes, the diodes are mounted on the number of patches, and the number of connectors are connected to the bias board and the number of patches; a control system capable of controlling a first portion of the plurality of mirrors on the polymer microtruss in the mirror array to direct a first portion of the millimeter wave signal to a detector, and capable of controlling a second portion of the plurality of mirrors on the polymer microtruss in the mirror array to direct a second portion of the signal away from the detector; an image processor capable of creating an image using the first portion of the signal detected by the detector; and a display device in communication with the image processor, wherein the image processor is capable of displaying the image on the display device.
