Paper Abstract

A medium power, narrow beam, electron gun is shown to produce a viable heat source for IR scenario simulation. The electron beam strikes a cryogenically cooled screen, producing a small infrared source against the cold background. Electronic deflection modulates and directs the beam, creating a real-time scenario simulation. Beam size and thermal spot spreading determine spatial resolution of the scene. Thermal relaxation time of the screen determines temporal resolution. Computer modelling is used to predict gun and screen performance. A series of experiments, used to confirm the predictions of simulation, and their results are described.
