Improved mathematical model for the registration of optical radiation in the television-term optical-electronic system, which differs from the known into account the nonlinear effect of the Ad-Hoc accumulation of signals on the volt characteristic of the photodetector. Based on the elaboration of mathematical models analyzed the influence of external factors and the accumulation time of the optical signal-those television receiver opto-electronic system of the linearity of its signal characteristics. Analytical expressions to optimize the process of continuous accumulation of optical signals on the photocathode of the receiver, depending on the intensity of radiation. Conclusions about the nature of the multiplicative effect of external noise of high intensity on the accumulation of the signal and the linearity of the voltaic receiver characteristics of optical radiation.
Keywords: optical-electronic system, a television receiver, the signal accumulation
