This paper will present the results and progress of AMRDEC'S development of two cold background, flight motion simulator (FMS) mountable, emitter array based infared scene projectors for use in hardware-in-the-loop systems simulation. The goal for this development is the ability to simulate realistic low temperature backgrounds for windowed/domed seekers operating in tactical and exo-atmospheric simulations. Two projectors have been simultaneously developed; the first represents a streamlined pathfinder version consisting of a Honeywell emitter array and refractive optical system contained within an FMS-mountable environmental chamber cooled to -55 degrees Celsius. The second system is the full-capability version including a cryogenically operated BRITE II emitter array, zoom optics, integrated steerable point source and high-frequency jitter mirror contained within a similar FMS-mountable environmental chamber. This system provides a full-FOV cold background, two dimensional dynamic IR scene projection, a high dynamic range independently steerable point source and combined optical path high frequency jitter control. Both projectors are designed to be compatible with operation on a 5 axis electric motor driven Carco flight motion simulator. Results presented will include design specifications, optical performance, samlple imagery, apparent temperature and proposed future improvements.
