Claim Text:
1. An electromagnetic sensor for imaging a sample, comprising: drive/sense electronics; a pixelated sensor array having an array of capacitive sensor electrodes that source and/or sense electric fields that interact with the sample, and wherein, the electrodes are individually drivable by the drive/sense electronics to establish a desired temporal and spatial pattern in which electrical properties of interaction between the electrodes and the sample are used to generate an image; and a sensor head and associated electronics for interfacing with the pixilated sensor array and drive/sense electronics, and for transmitting the electrical properties of the electrodes to a computer for generation of the image, where in an active mode, at least a portion of the electrodes within the array of electrodes are individually drivable by independent voltage or current sources to excite the individual electrodes.
