Line 20:

\Gamma = \left\{ \sum_{i=1}^n a_i u_i \; | \; a_i \in\Bbb{Z} \right\}

where the vectors <math>u_i</math> are chosen to satisfy <math>\langle u_i, v_j \rangle = 2\pi\delta_{ij}</math>. An example of a sampling lattice is a [[hexagonal lattice]] depicted in Figure 1. The corresponding reciprocal lattice is shown in Figure 2.
