| 20110133090 | Method of Detecting Organic Materials Using Terahertz Spectroscopy - Disclosed herein are methods of detecting organic materials, and more particularly, methods of detecting organic materials using terahertz spectroscopy. The method of detecting organic material using terahertz spectroscopy includes suspending organic material in a medium to form a sample; irradiating the sample with an illumination beam of electromagnetic radiation, the illumination beam having a plurality of frequencies in the range of about 100 GHz to about 2 THz; detecting radiation transmitted through and/or reflected from the sample; and, analyzing the detected radiation to identify the organic material, wherein the medium is selected from the group consisting of agar, guar gum, gellan gum, carrageenan, xantham gum, fibrous sodium pectate, and other agar substitutes. | 06-09-2011 |
