Method and apparatus for compact birefringent interference imaging spectrometer
First Claim
1. A portable system for obtaining a spectrum of a sample, comprising:
- 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 rejection filter for blocking the first plurality of photons from entering a first filter;
said first filter for receiving the collected scattered photons and providing therefrom filtered photons; and
a first photon detector for receiving the filtered photons and obtaining therefrom a spectrum of the sample.

56. A method for obtaining plural spectra of a sample using a hand-held device, comprising the steps of:
-
providing a sample; illuminating the sample with a first plurality of photons to thereby produce photons scattered by the sample; illuminating the sample with a second plurality of photons to thereby produce photons emitted by the sample; collecting the scattered and the emitted photons; blocking the first and the second plurality of photons from entering a polarization beam splitter; separating the scattered and the emitted photons each having a first polarization from the scattered and the emitted photons each having a second polarization using the polarization beam splitter; receiving the scattered and the emitted photons each having a first polarization and providing therefrom first filtered photons; receiving the first filtered photons and obtaining therefrom a first spectrum of the sample; receiving the scattered and the emitted photons each having a second polarization and providing therefrom second filtered photons; and receiving the second filtered photons and obtaining therefrom a second spectrum of the sample. - View Dependent Claims (57, 58, 59)
