Abstract

Aimed at improving the detection ability of the night vision system, a new method to design the optimum spectral band is presented. The new method uses MRC (Minimum Resolvable Contrast) as the criteria of the system performance and brings the spectrum characteristic of the scene and the night vision system into the MRC evaluation. According to the MRC variety of the night vision system under the different working spectral bands, the optimum spectral band is the one which can maximize the scent contrast and doesn't obviously decrease the cut-off spatial frequency of the MRC curve. Finally by the design method and the MRC model, the optimum spectral band of a night vision system example under the special scene is given.
