Dual readout—strip/pixel systems

3D-electrode pixel detectors are proposed in which the bias electrodes are connected to form a strip readout on the same or opposite side of the sensor. It can provide a fast trigger and significantly increase spatial resolution in both directions. This combination is also possible with double-sided processing in planar technology. A second paper (“Dual Readout—3D Direct/Induced-Signals Pixel Systems”) will cover another means of increasing spatial resolution without duplicating the complex pixel electronics.
