Abstract
An apparatus including: a first resistive screen extending in a first direction and a second direction; a second resistive screen extending in the first direction and the second direction and separated from the first resistive screen; a first reference resistor; a voltage source configured to apply a voltage across a series combination of the first reference resistor and the first resistive screen; and a voltage detector configured to measure a first voltage across the reference resistor.
