Abstract

With the introduction of the night-vision goggle (NVG) into vehicle cockpits, the transfer of visual information to the observer became more complex. This problem stems primarily from the fact that the image intensifier tube photocathode was sensitive to much of the visible spectrum. NVGs were capable of sensing and amplifying visible cockpit light, making the observation of the scene outside of the cockpit, the primary use for NVGs, difficult if not impossible. One solution was to establish mutually exclusive spectral bands; a band of shorter wavelengths reserved for transmission of visible information from the cockpit instrumentation to the observer and a longer wavelength region left to the night vision goggle for imaging the night environment. Several documents have been published outlining the night vision imaging system (NVIS) compatible lighting performance enabling this approach, seen as necessary for military and civilian aviation. Recent advances in short wave infrared (SWIR) sensor technology make it a possible alternative to the image intensifiers for night imaging application. However, application-specific integration issues surrounding the new sensor type must still be thoroughly investigated. This paper examines the impact of the SWIR spectral sensitivity on several categories of lighting found in vehicle cockpits and explores cockpit integration issues that may arise from the SWIR spectral sensitivity.
