Paper Abstract

An analytical model is developed suitable for optimizing the choice of the design parameters that govern the extent of spatial filtering and artifact generation (aliasing) in dynamic infrared scene projection systems. The filtering and sampling processes occurring at both the scene renderer and infrared projector are examined quantitatively in such a way that they can be compared to the filtering and sampling processes occurring within the imaging infrared unit-under- test. Graphs and formulae are included that enable the optimal choice of the relevant system parameters and allow quantitative assessment of the additional sources of spatial filtering and aliasing present within the infrared projection system.
