Acousto-optic devices

Acousto-optic devices use sound waves to control light. They typically consist of a crystal that can change how light travels through it when sound waves pass through. By adjusting the sound waves, these devices can modulate, deflect, or filter light beams. This technology is commonly used in various applications, such as laser printers, optical scanners, and telecommunications, allowing for precise control of light in optical systems. Their ability to manipulate light makes them valuable tools in imaging, signal processing, and even scientific research.
