Query: A genetic algorithm approach to reconstructing spectral content from
  filtered x-ray diode array spectrometers   Filtered diode array spectrometers are routinely employed to infer the
temporal evolution of spectral power from x-ray sources, but uniquely
extracting spectral content from a finite set of broad, spectrally overlapping
channel spectral sensitivities is decidedly nontrivial in these underdetermined
systems. We present the use of genetic algorithms to reconstruct a
probabilistic spectral intensity distribution and compare to the traditional
approach most commonly found in literature. Unlike many of the previously
published models, spectral reconstructions from this approach are neither
limited by basis functional forms, nor do they require a priori spectral
knowledge. While the original intent of such measurements was to diagnose the
temporal evolution of spectral power from quasi-blackbody radiation sources,
where the exact details of spectral content was not thought to be crucial, we
demonstrate that this new technique can greatly enhance the utility of the
diagnostic by providing more physical spectra and improved robustness to
hardware configuration for even strongly non-Planckian distributions.
