ABSTRACT:
Orthogonal thermographs of a target one desires to simulate are taken, are eproduced on a plastic medium, and are formed onto a model of the target. The model is the same scale as the thermographs, and is transparent to radiation from internal sources. These sources are baffled, visible-light sources and correspond to the thermally-emissive portions of the target. The thermographs are covered by a paint or filter material which passes only a preselected portion of the source spectrums. A visible-light television camera without a filter which passes this portion will thus yield a signal which will appear as an infrared image on a television monitor. At the same time, another visible-light television camera with a filter will yield a signal for a visible-light target simulation, when the model is illuminated from outside with visible light.
