Claim:
1. A measurement tool for measuring a characteristic of a sample, the measurement tool comprising: an integrated computational element (ICE) comprising a plurality of layers stacked along a first axis, wherein each of the layers has a plane perpendicular to the first axis, the layers being laterally offset from each other along the first axis, and a constitutive material of each of the layers being electrically conductive and patterned with a corresponding pattern, wherein an arrangement of the patterns with respect to each other is related to a characteristic of a sample, wherein the plurality of layers of the ICE comprises a first layer of electrically conductive material patterned with a first pattern and a second layer of electrically conductive material patterned with a second pattern, and the arrangement of the first and second patterns with respect to each other comprises the lateral offset in the plane perpendicular to the first axis, such that the offset causes a Moiré pattern related to the characteristic of the sample.
