With the introduction of the night-vision goggle (NVG) into vehicle cockpits, the transfer of visual information to the observer became more complex. The problem emanated from the image intensifier tube photocathode spectral response. NVGs were capable of sensing and amplifying visible cockpit light, making observation of the scene outside of the cockpit, the primary use for NVGs, difficult. Over the years, several documents were published outlining night vision imaging system (NVIS) compatible lighting performance. These documents limited the permissible amount of light visible to image intensifier tubes that cockpit displays could emit, enhancing pilot visual performance. Recent advances in short wave infrared (SWIR) sensor technology make it a possible alternative to image intensifiers for night imaging application. However, while popular SWIR cameras are not particularly sensitive to visible light, they may be sensitive to other display emissions not attenuated by state-of-the-art NVIS filters. This paper examines the possibility of expanding the traditional treatment of vehicle cockpit compatibility to include new, novel vision enhancement devices yet to be designed and vehicle cockpit geometry.
