| Abstract |
Technology to investigate hidden chemical information of components inside container is attracted attention in airport security, pharmaceutical process, chemical synthesis process and medical field. This technology requires non-destructive and rapid identification of the internal components in the container. Spatially offset Raman spectroscopy (SORS) is a potential candidate for investigating the chemical information of hidden substance in a container. SORS is a method of measuring Raman signal along the distance between the laser irradiation point and the detection point. The Raman signal generated by the penetration of the laser into the inside is observed to be relatively stronger as the distance increases. Therefore, SORS not only can quickly and nondestructively identify the structure of a chemicals, but it is also useful for detecting hidden substances inside containers. In this study, we fabricated SORS fiber optic probes to facilitate SORS measurements. The SORS fiber optic probe is designed so that detection point is located at offset of 5 and 10mm on both sides from the center laser is irradiated. The Raman signal obtained from the SORS fiber optic probes was subjected to internal reference subtraction to remove the Raman signal of the container. We have used a fiber optic probe to measure and database various chemicals in the container. SORS measurements using fiber optic probes have proven to be non-destructive and quick to measure the material in the container. |
