Abstract
Official abstract text for this publication.
A sensing circuit and method is disclosed, which may comprise a plurality of transmitting or receiving elements each defining a pixel location defined by a gap between the respective one of the plurality of transmitting or receiving elements and a single element of the opposing type to the respective transmitting or receiving element, and a controller configured to provide or receive a probing signal to or from a group of at least two of the plurality of transmitting or receiving elements, at the same time, thereby increasing the effective area providing the transmitting of or the receiving of the probing signal for each pixel location imaged. The group of transmitting or receiving elements may form a symmetric pattern, which may be centered on the pixel location. The plurality of transmitting or receiving elements may form at least one linear pixel array with the respective single receiving or transmitting element.
