The article proposes a classification of facet systems of technical vision. According to this classification, all systems are divided into groups depending on the type of optical system, which can be represented as a combination of microlenses, optical fibers and an objective, and the type of photoreceptors - matrix, linear or single-element photoreceptor. The construction of facet systems was considered, an analysis of their advantages and disadvantages was performed, recommendations were formulated regarding the choice of a facet system of technical vision.
