Abstract
In this Bureau of Mines report, the optical detection of fires and explosions is considered fundamentally. The measured spectral radiances from methane-air ignitions are compared with the background irradiances from stray and ambient sources, and with the spectral sensitivities of various snesors. The comparison naturally suggests the optimum spectral ranges and signal processing logic that can uniquely characterize the ignition event. Both ultraviolet (uv) and infrared (ir) are considered. Several alternate sensing methods are proposed and discussed. The development and testing of an ir system designed for use in ignition suppression devices in mines are described.
