The work is based on the concept of detectors fields based on the possibility of the formation of two-zone structures on the image field, their movement and overlap. The mechanism of the drift of the detectors field is considered.
In the article, a mathematical model of the drift is constructed, which allows identifying it at different positions of the illumination boundary on the detectors field by the reactions of the detectors. The initial state of the elementary detector is described. Analyzed all possible options for the mutual location of the detector area and the limits of illumination. Base cases were identified, and expressions for calculating the reactions of the central and peripheral zones of the detector were found. The mechanism of displacement of the detector in the process of drift is investigated. A table of transitions between the base cases was compiled to determine the response of the drifting detector to an arbitrary light limit.
The constructed model of the drift of the detectors field makes it possible to ensure a significant reduction in computational costs both in the software implementation of the drift and in the implementation of the mechanical displacement elements of the analyzed scene.
