The variety of applications, heterogeneity of physical processes taking place during the passage of information through modern photodetector devices, create significant difficulties in conducting field experiments on them during their development and research. This is especially evident at the stage of development of the advance project, when there is absent only the photodetector itself, but also the very concept of building the device. In this case, it is especially important to carry out the process of mathematical modeling and build a computer model of the proposed photodetector in order to select its layout, optimal parameters and operating modes. This paper describes the development of a computer model of a matrix photodetector or FPA starting from the first stage, the stage of creating a primary vision of an object or system. At this stage, the main components of the FPA, the relationship between them, input, output and control signals were determined. Thus, a conceptual model was built, which reflects in an idealized form the composition and principle of operation of the FPA. At the next stage, on the basis of the conceptual model, a mathematical model of the FPA was developed, checked for adequacy and concluded that the expected deviation of the characteristics of the model from the parameters of the real device was small. Finally, at the last stage, a software implementation of the mathematical model in MATLAB was carried out and a computer model was obtained. Further, in order to check the performance of this computer model, the dependences of the image quality of the FPA on various physical and structural parameters were investigated and it was concluded that this model can be used at the initial stage of the development of the FPA to develop technical requirements for it and compare different layout options.
