Solving the Synchronization Problem Using a Photonic Frequency Locked Loop System for Control Systems in Technological Processes

A new approach to the construction of a holographic photonic frequency locked loop (FLL) system for control systems and technological processes automation is proposed. We offer to use elements of holographic photonics to design the FLL system. It is shown that the proposed system provides increased speed, extension of the capture and retention bands, as well as decrease in the amount of residual frequency alignment. A variant of a block diagram for the holographic photonic FLL system is developed and its operation is described. We have carried out mathematical modeling and studied interferogram parameters formed by a holographic interferometer. Graphical dependences are constructed, and their analysis allowed us to state the effectiveness of using the holographic interferometer in the developed version of a schematic implementation of the holographic photonic FLL system.
