Abstract:

Attempts at devising training simulator out-the-window night time displays that can be effectively used by a night vision goggle NVG- wearing trainee have yielded NVG display systems of questionable fidelity, stability, andor repeatability. The physics-based approach reported here first characterizes a display in terms of its absolute dynamic output range for night vision imaging system NVIS radiance and then, using that characterization, maps, as possible, to-be-displayed NVIS radiance values of simulated scene objects on to the display itself. Treatment of NVG-specific phenomena, such as halos, is discussed, as are considerations of NVIS cross-illumination in multiscreen displays. Modifications to an existing NVG simulation software module SensorHost to accommodate display of NVIS radiance are described. Example NVIS characterizations of various off-the-shelf simulator display systems are detailed.
