1. An analytical device comprising:

  • a source assembly comprising a plurality of sources, the sources spatially arrayed pseudo-randomly in at least a first dimension;

    a detector assembly spaced from the source assembly, the detector assembly comprising a number of sensors sensitive to an output of the plurality of sources, anda dispersion element positioned in a path between at least one of the plurality of sources and at least one of the sensors to disperse the output of at least one of the plurality of sources,wherein the dispersion element comprises a magnetic assembly positioned to create a magnetic field in the path between at least one of the plurality of sources and at least one of the sensors to disperse the output of at least one of the plurality of sources.
