Research Abstract |
To detect minor components in breath, a spectroscopic measurement system using a quantum cascade laser and a hollow optical fiber was developed. By optimizing the optic system and signal processing method, quantitative measurement of ppm-order gas component was successfully demonstrated. Subsequently, to devlop a cavity-ring-down spectroscopy system having further high sensitivity, hollow optical waveguides with inner dielectric layers were fabricated. By forming multiple dielectric layers on the inside, the transmission losses are largely decreased compared to common hollow waveguides with a single dielectric layer.
