摘要
An optical filter and control system that provides graduated adjustment of the optical characteristics, which render a display compatible with the use of Night Vision Goggles. The control system enables real time adjustment of the filter's optical characteristics during operational use of the display. The filter is actively controlled to adjust its optical characteristics either by temperature adjustment and/or by physically altering the filter's angle of incidence relative to the observer or display illumination system. The characteristics are adjusted to achieve either better color rendering by the display or to achieve lower radiance within the NVG region of sensitivity. The active control system can either be adjusted by operator input or controlled by a built in algorithm, which is based upon operational conditions.
