1. An imaging system comprising:
- a sensor array having a plurality of modulated slots for measuring an electric field from an object, said slots being positioned at locations corresponding to a defined spatial domain located remotely from the object, said slots each providing an output signal representative of the electric field detected at the respective location of the slot;
a receiver operatively connected to the array for receiving the output signals from the 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; and
a display for displaying an image of the multi-dimensional profile.

Abstract
A sensor array having a plurality of modulated slots for microwave and/or millimeter wave imaging. The locations of the slots in the array define a spatial domain away from an object for detecting an electric field from the object. Each of the slots outputs a signal representative of the measured field and the location of the slot. A processor decodes the signals and generates an image of the object.
