1. A biometric system comprising:

  • one or more illumination sources configured to illuminate at least a portion of a target space;

    a first imager configured to receive light from at least a portion of the target space under a first optical condition;

    a second imager configured to receive light from at least a portion of the target space under a second optical condition, wherein the first optical condition is distinct from the second optical condition; and

    an analyzer communicatively coupled with the one or more illumination sources and the plurality of imagers, wherein the analyzer is configured to control the operation of the one or more illumination sources, the first imager, and the second imager in order to produce a multispectral image of a skin site of a purported individual placed within the target space from the light received at first imager and the second imager, wherein the analyzer is configured to derive spatially distributed multispectral characteristics from the one or more multispectral images.
