Abstract:
1. An imaging system comprising: a conductive surface having a plurality of slots formed therein at locations corresponding to a defined spatial domain located remotely from an object; a plurality of active elements for modulating the slots, wherein each of the slots has at least one of the active elements connected thereacross for selectively modulating the slot, wherein the modulated slots comprise a sensor array for measuring an electric field from the object, and wherein each of the modulated slots provides an output signal representative of the electric field detected at the respective location of the modulated slot, and wherein the at least one of the active elements connected across each of the slots selectively changes the resonant frequency thereof; a receiver operatively connected to the array for receiving the output signals from the modulated slots; a processor configured to generate a multi-dimensional profile representative of the object in the defined spatial domain based on the received output signals from the modulated slots; and a display for displaying an image of the multi-dimensional profile.
