Abstract

This study explores the generation of complex scanning patterns using Risley prisms for advanced optical applications. Risley prisms, composed of two independently rotating wedge prisms, allow precise control of light beam deviation. We investigate the generation of spirals, polar roses, epitrochoids, and hypotrochoids, highlighting their distinct fill factors, probability densities, and scanning velocities. These patterns are optimized for scanning different regions with high precision. The implementation of these methods in sequential and parallel systems is discussed, emphasizing the trade-offs between data processing complexity and scanning efficiency. This research provides valuable insight into optimizing scanning patterns and integrating real-time data analysis to improve efficiency in optical systems.
