Abstract
Sensor independent display characterization system spectrally characterizes a display system to measure radiant power emitted by the display system that displays a video image to a trainee pilot during sensor stimulation. A sensor spectral response for each wavelength produced by the stimulated sensor is determined. A stimulated luminance for each color level of the displayed image or for a range of color levels is computed. A color look up table that maps computed stimulated luminance to a set of stimulating color values is generated. When a trainee pilot looks at the displayed image using a sensor having a sensor response that was used in computing the stimulated luminance, the pilot will see an image that was created by simulated spectral rendering. The displayed image is an accurate, display and sensor independent image that the pilot can see during the real flight.
