| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | As a low-volume and long-path gas cell for gas analysis system based on terahertz time-domain spectroscopy (THz-TDS) system, a hollow optical fiber with an inner dielectric coating is proposed. The dielectric-loaded fiber was fabricated by depositing a metal thin film on a polymer film tube. Although NH3 gas was successfully detected by using the fiber with a THz-TDS system, separating absorption peaks of NH3 and water vapor was difficult. By improving frequency resolution in Fourier transformation, those two peaks were separated and furthermore, by introducing a longer hollow-optical fiber, the system sensitivity was improved and the detection limit of 0.5% was obtained for NH3 gas. | |
