Abstract: Simulation of detector operation can be a valuable tool in optimizing design before recourse to cutting metal, and, if successful, can significantly reduce the requirement for design iteration. We describe this process as applied to the reduction of spatial non-linearities in electronic charge division image readout devices. Several theoretical analyses of the non-linearities expected in such devices have been previously undertaken; however, all suffered from the inability to analyze the perimeter pattern areas where the electrode geometry does not bear simple analytical description. We present a technique whereby an arbitrary radial charge distribution may be convolved with any multiple electrode structure, which can be defined as a set of closed polygons, to calculate total charge deposited on each electrode. This technique can be used for electronic charge division image readouts to accurately determine the effect of arbitrary electrode perimeter designs; the major cause of non-linearity in these devices.
