13.1 Introduction
Spectral imaging methods have long been used in the fields of astronomy [1],
remote sensing [2], and chemical compound analysis [3], to elucidate the com-
position and characteristics of terrestrial and atmospheric elements. In recent
years, spectral imaging has found utility in microscopy applications ranging
from spectral karyotyping [4], general cell visualization [5], and cell trafficking of
variously colored fluorescent proteins [6].
Spectral imaging is the combination of two mature technologies: spectros-
copy and imaging. In recent years, spectroscopy has found increased
