Abstract
A method and apparatus of obtaining a spectral image of a plurality of predetermined chemical species. A sample is illuminated to produce photons. These photons are collected to produce a plurality of images for each predetermined chemical species, wherein each image comprises a frame consisting of a plurality of pixels. A wavelength range is identified wherein a chemical species exhibits a unique absorption of radiation. Pixels are identified that do not comprise the chemical species. The steps may be repeated for a plurality of chemical species. If more than one chemical species is present, the contribution of each in a pixel is separated and separate spectral images of each species is composed.
