1. A method for obtaining data from a spectral source, comprising:
identifying an environment that is capable of generating spectral information;
obtaining the generated spectral information from the environment from one location of the environment;
for the spectral information obtained from the one location, splitting the generated spectral information into a plurality of spectral data units that are tuned to register particular bands of wavelengths from a visible electromagnetic spectrum, wherein the splitting the generated spectral information includes rotating a shutter to enable capturing the particular bands of wavelengths for each of the spectral data units;
capturing the particular bands of wavelengths for each of the spectral data units in separate storage entities;
separately and in parallel processing each of the particular bands of wavelengths of the plurality of spectral data units; and
combining an output of the processing to produce a complete processing of the particular bands of wavelengths of the plurality of spectral data units, the complete processing defining a quantification of the environment from the one location.
