Laser verification and authentication raman spectrometer (LVARS) detecting the stokes and/or anti-stokes emission

A method to verify the origin of an unknown sample of a document comprising the steps of:

• exposing a sample of unknown media simultaneously to multiple wavelengths from laser sources in order to create Raman emissions from the sample;
• detecting the Raman emissions from the sample using two or more detectors each with a specific wavelength detection region, wherein the Raman emissions comprises at least one Stokes component and/or at least one Anti-Stokes component;
• and
• comparing the detected Raman spectra with Raman spectra previously stored in a database.

A computer readable medium containing program instructions for verifying the origin of an unknown sample, said program instructions comprising instructions for:

• exposing a sample of unknown media simultaneously to multiple wavelengths from multiple laser sources;
• reading a Raman spectra of the sample of the unknown media through a variety of detectors each with a specific wavelength detection region using Raman spectroscopy, wherein the Raman spectra comprises at least one Stokes component and/or at least one Anti-Stokes component;
• and
• manipulating mathematically at least one of the Stokes component and/or at least one of the Anti-Stokes component.

A system for verifying the origin of an unknown sample of a document comprising:

• a chamber for exposing a sample to a multiple wavelength laser source in order to create Raman emissions from the sample;
• two or more detectors each with a specific wavelength detection region for detecting the Raman spectra, wherein the Raman spectra comprises at least one Stokes component and/or at least one Anti-Stokes component;
• and
• a computer for manipulating mathematically at least one of the Stokes component and/or the Anti-Stokes component.
