| Research Abstract |
Remote sensors for thermometry and gas monitoring were developed by the use of infrared optical fibers. Chalcogenide glass fibers (As-S,Ge-As-Se, and Ge-As-Se-Te) and polycrystalline silver halide fibers (AgClBr) were fabricated for this purpose. Low temperature was measured accurately due to the high transparency of the fibers in the mid-infrared region. A bundle of chalcogenide glass fibers was also developed and used for the transmission of thermal images. In the experiment of gas monitoring, such gases as propane, butane, and alcohol were measured successfully by the use of a Fourier-transform infrared spectrometer. An infrared CCD camera was also used to observe the distribution of gases. It was demonstrated in this study that the infrared optical fibers are useful for remote sensing that is required in the industrial measurements and medical diagnostics.
