Popis: The detection model based on the fluctuation theory can determine only the upper limit in the performance of image intensifier systems for night vision. Our laboratory and field experiments show that the signal to noise ratio of the final image is influenced by the fluctuations in the number of incident photons on the image intensifier photocathode, the quantum efficiency of the photocathode, the value of noise generated in the amplification process and the modulation transfer function for the atmosphere and optical components.
