Abstract

Sweeping scanning scheme of a hot gas in the task of infrared tomography is formulated. Two diagnosis regimes are used: the active one (ON) – with included source and the passive one (OFF) – without it. Two integral equations are deduced concerning the absorption coefficient k and the Planck function B of a medium (by which it is possible to calculate the temperature profile of a medium T).

Keywords: IR tomography, integral equations of radiation transfer, active and passive diagnosis regimes, sweeping scanning, absorption coefficient, temperature profile
