Abstract
A hyperspectral imaging system is tested in the lab to allow a determination of its response to the emission from a simulated target, of certain wavelengths of radiation which the imaging system will be using during target determination. A broadband IR wavelength generator is used to generate a multiplicity of wavelengths representing the target and an emissions simulator is used to generate wavelengths representing target emission of hot gases. An AOTF is used to delete one or more target wavelengths, and to add one or more emission wavelengths, from and to the transmission path to the imaging system.
