Abstract

In this study, we designed a fast steering mirror for precise beam alignment between a transmitter and receiver in optical communication systems.design variables were optimized using an optimization method and validated using a finite element method analysis. The control results showed a driving range of 1.5 °, a high resolution of 0.005 °, and steady state error is less than 1%. This design approach, which combined optimization algorithms and high-speed precision control, significantly improved the performance of laser-beam alignment systems. The increased alignment precision, and lower error rates were expected to be extremely beneficial for various applications requiring reliable and accurate optical communication.
