The optical detection of an explosion or fire event is considered quantitatively in terms of the source radiance, background or stray irradiances, and the spectral responsivities of the available sensors. The infrared spectral source radiances from spherical methane-air "ignitions" were measured and the data analyzed. They serve as the basis for the development of a new detector that uses wavelength selection about the 4.4-Um co2 band to detect fires and explosions rapidly and reliably and to discriminate effectively against false sources. Typical radiance data from hydrocarbon pool flames are also considered.
