ABSTRACT:
The disclosure relates to a method and apparatus for a compact birefringent interference imaging spectrometer. More specifically, the disclosure relates to a portable system for obtaining a spectrum of a sample. The portable system may include a first photon emission source for illuminating the sample with a first plurality of photons to thereby produce photons scattered by the sample; an optical lens for collecting the scattered photons; a filter for receiving the collected scattered photons and providing therefrom filtered photons; a first photon detector for receiving the filtered photons and obtaining therefrom a spectrum of the sample; and a rejection filter for blocking the photons from said first photon emission source from entering said first photon detector. The disclosure additionally relates to methods of using such portable systems.
