In this paper, the statistical characteristics of output signals in optoelectronic
 systems with a limited dynamic range are considered. The experimental results
 concerning noises probability densities are adduced. It has been shown that the law of
 output signal distribution depends on attenuation factor of neutral filter used for matching
 the dynamic range. The output signal distribution law is well approximated by the steady
 distributions with characterization index 0 < α < 2. Using the stable law as a limiting one
 allows to avoid the contradiction between experimental data and common mathematical
 models of signals based on the Poisson and Gaussian statistics and to reduce weak
 signals detection errors in optoelectronic systems with implementation of neutral filters
 for matching the dynamic range.
