Formulation of the problem. Accurate mathematical models of frame-by-frame matrix photodetectors are critical to understand and explain their principles of operation, to develop and control them. The signal characteristics (“transfer characteristics”) of these photodetectors and their components are also required, without which it is difficult to analyze the characteristics of the photoconductor.

Purpose of the article. Laying down methods for creating mathematical models of frame-by-frame matrix photodetectors’ components. Laying down the system of these parts’ characteristics simplifying process of creating such models and models of television cameras based on these photodetectors.

Results. A simple method of mathematical modeling of television cameras and their components is proposed to explain and analyze the real physical effects in these devices. This method provide the steady way for calculation characteristics of matrix photodetectors and their competitive comparison.

Practical significance. Obtained results could be used in the development and testing of frame-by-frame matrix photodetectors.
