Paper Abstract

Night vision devices are important tools that extend the operational capability of military and civilian flight operations. Although these devices enhance some aspects of night vision, they distort or degrade other aspects. Scintillation of the NVG signal at low light levels is one of the parameters that may affect pilot performance. We have developed a parametric model of NVG image scintillation. Measurements were taken of the output of a representative NVG at low light levels to validate the model and refine the values of the embedded parameters. A simple test environment was created using a photomultiplier and an oscilloscope. The model was used to create sequences of simulated NVG imagery that were characterized numerically and compared with measured NVG signals. The sequences of imagery are intended for use in laboratory experiments on depth and motion-in-depth perception.
