1. A system, comprising:
a calibration system, comprising:
a support structure movable over an array comprising elements;a calibrator secured to the support structure to obtain information at selected locations in relation to the array, wherein the locations are along a first axis with substantially no change along second and third axes, wherein the first, second, and third axes define a three-dimensional space; anda calibration module comprising a computer processor to compute a sum of voltages from the information for the locations of the calibrator with respect to the array for determining a level of calibration for the elements in the array, wherein the sum provides a virtual super-element that runs a length of the array along the first axis.
