ABSTRACT
An analysis of current approaches used in the design of optical recording systems for modulation disks has been conducted. By adapting mathematical models, software algorithms were developed to transform code sequences represented in polar, homogeneous, and parametric coordinate systems, and the unique characteristics of each approach in developing a universal method for ensuring accurate and efficient modulation pattern transformation were established. It was noted that the polar coordinate system is the most suitable for practical applications in code sequence transformations. Its ability to effectively represent circular and symmetrical structures, as well as the convenient representation of objects with radial symmetry, provides advantages in the creation of modulation disks. As a result of the study, effective software solutions for automating data processing in the formation of modulation patterns were identified. The implementation of the developed software algorithms for the presented approach involves adapting the code sequence to the current metric within the design of an optical system based on modulation disks. The presented methodology ensures the ability to transform code sequences regardless of the chosen coordinate system, which significantly enhances its flexibility and versatility for practical applications.
