Standoff detection of chemical agents may be enhanced with the capability to measure an image of the agent concentration. The use of an imaging Fourier-Transform Spectrometer to perform these measurements is extensively modeled in order to predict its ultimate capabilities. The model developed allows one to determine the optimal configuration of the instrument, taking into account the precise characteristics of realistic and existing hardware. The model is first based on the calculation of radiative transfer from the scene into the instrument up to the imaging detector. Standard performance models of FTS are improved to include the particular features of imaging FTS operated with infrared cameras. The infrared focal plane arrays have their own constraints that are taken into account in the model.
