Raman spectroscopic system for detecting human body fluid traces on an interfering substrate

A method of utilizing Raman spectroscopy to detect and identify human body fluids within a fluid sample on a light scattering substrate, comprising:

• scanning a fluid sample with a portable Raman spectrometer having a body thereof including a computer platform in selective communication with other computer devices across a network, the Raman spectrometer selectively receiving and recording a light scatter from a laser selectively projecting a sensing laser;
• collecting spectroscopic data from a fluid sample at the computer platform of the spectrometer, the fluid sample upon a light scattering substrate;
• transmitting the spectroscopic data from the computer platform of the spectrometer to a processor across a network, the processor in selective communication with the computer platform of the body across the network;
• analyzing the received spectroscopic data at the processor;
• and
• isolating, at the processor, an interfering light scatter from the spectroscopic data to thereby produce chemical analysis data for the fluid sample.

A device for detecting human body fluid traces in a fluid sample on an interfering substrate, comprising:

• a body, including:
• a computer platform in selective communication with a network;
• a spectrometer selectively receiving and recording a light scatter;
• a laser selectively projecting a sensing laser light;
• a focusing optic through which passes the sensing laser light and the light scatter;
• and
• wherein the spectrometer projects the sensing laser light to selectively probe a remote fluid sample on a substrate that produces interfering light scatter, the spectrometer thereby obtaining spectroscopic data therefrom that contains the interfering light scatter, and the spectroscopic data is relayed to the computer platform for analysis, and
• wherein the computer platform further configured to isolate the interfering light scatter from the spectroscopic data to thereby produce chemical analysis data for the fluid sample.
