Annotation. This article discusses the issues of optoelectronic discrete converters (ODC) of any type - longitudinal or transverse movement of the external modulating body (EMB); are transformed when changing the parameters of the luminous flux Ф₀ in the corresponding light guides from concentrated and radiation sources (RS) or a distributed radiation source (DRS). Further light fluxes Ф₀ falling on the corresponding radiation receiver (RR), their parameters change and the output voltage U_out in the measuring circuits changes.
Key words: radiation sources, radiation receivers, measuring circuits, light guide, optical fibers, operational amplifiers.


Introduction
In connection with the development of such important sectors of the economy as mechanical engineering, metallurgy, oil and gas, chemical, industrial, construction, food industry and others, it is important to provide them with modern discrete displacement transducers that allow them to monitor and manage such important quantities as liquid levels, speed and flow flows of gases and liquids, as well as automate the processes of automatic accounting of piece goods, products, goods, blanks and semi-finished products, which allows you to objectively analyze the economic activities of enterprises and plan their further development.
The variety of specific features of monitoring and control objects put forward a set of requirements for discrete converters of object parameters: high sensitivity , accuracy, reliability, sufficient noise immunity, manufacturability, small dimensions and the ability to fully automate the monitoring and control of object parameters using microprocessor systems. An analysis of existing discrete optoelectronic displacement transducers shows that to solve the above problems for monitoring and control, optoelectronic discrete displacement transducers based on hollow and fiber light guides are the most acceptable and promising. In this regard, the improvement and development optoelectronic discrete displacement transducers based on hollow and fiber light guides is an urgent task.
