1. A biometric sensing device having a sensing pad for accepting a biological surface, said sensing pad having a plurality of sensing elements, said plurality of sensing elements forming sets of rows and sets of columns, said rows and said columns each having at least two sensing elements, each two of said rows and each two of said columns being individually spaced from each other, said rows and said columns grouped together to form at least one linear sensing array, the biometric sensing device comprising: a first linear sensing array, the linear sensing array being regularly spaced and having a first known spacing between rows thereof; a second linear sensing array, the linear sensing array being regularly spaced and having a second known spacing between rows thereof; wherein a third spacing between the first and second regularly spaced linear sensing array is other than an integer multiple of the first known spacing.
