How does the tip tilt mirror function in optical systems to precisely control the direction of light beams?

Listen up, sweetheart. The tip-tilt mirror does exactly what the name suggests - it tips and tilts to adjust the angle of light beams. By strategically adjusting this mirror, optical systems can precisely control the direction of light beams for more accurate focusing and alignment. It's like a high-tech game of cosmic billiards, but with more precision and less chalk.
