Abstract
Research was conducted to design, develop, and construct a prototype carbon monoxide detector for use in atmosphere monitoring in underground metal and nonmetal mines. A device is described that is based on the measurement of infrared absorption at 4.65 Micrometers. The unique feature of the nondispersive infrared instrument is contained in the optical design, which includes a confocal cavity, increasing the effective optical path length by a large factor, thus greatly reducing the required package size. Tests of a breadboard model are described that show cavity gains of 10 with noise levels equivalent to 2 to 10 ppm carbon monoxide.
