1. An apparatus, comprising:

  • a structure that provides for relative motion between an object and a filter assembly, wherein the object is an area within a larger object; and

    an encoding component that includes the filter assembly, the filter assembly configured to receive light emanating from objects in the structure;

    wherein the filter assembly is adapted to provide output light in response to input light that is within an application'"'"'s range of photon energies and that is emanating from the object moving relative to the filter assembly;

    wherein the filter assembly includes a set of positions, each having a respective transmission function within the range;

    wherein the object'"'"'s relative motion with respect to the filter assembly include at least two segments from which respective positions in the set receive light emanating from the object; and

    wherein the filter assembly includes a longitudinal sequence of filter regions, the filter regions including first regions of a first filter type and second regions of a second filter type, the first and second filter types transmitting respective first and second spectral ranges of light, the first and second spectral ranges being sufficiently different from each other that the difference causes time variation in the output light while the object travels through the respective segments.
