In modern optical systems, real-time beam steering has become a critical capability, enabling dynamic control of laser beams for applications ranging from microscopy to laser communications. Among the technologies enabling this functionality, acousto-optic deflectors (AODs) stand out due to their speed, precision, and reliability. Understanding how AODs facilitate real-time beam steering provides insight into their transformative role in advanced photonics. https://www.cq-smart.com/acousto-optic-deflectors-principles-applications-and-resolution
