The article presents the problem of methane detection with a multispectral infrared camera. It also presents some commercially available devices and method used for the detection of chemical substances (gases). The project of a multispectral infrared camera and theoretical calculation regarding the possibility of methane detection is also reported in this paper. The calculations included the properties of optical path: camera-cloud of methane background. Verification of theoretical results was made during laboratory measurement. Some initial results of methane detection are also presented.read more

Gaussian model for emission rate measurement of heated plumes using hyperspectral data
TL;DR: In this paper, the authors used the radiative transfer equation (RTE) to relate the spectral intensity of a pixel to Gaussian distributions of volume fraction and temperature within the plume, along a line-of-sight that corresponds to the pixel, whereas previous techniques exclusively presume uniform distributions for these parameters.
