Acousto-Optics is an exciting branch of technology that studies the acoustic interactions between sound waves and ultrasound waves, specially the diffraction of visible light via an optics lens. These waves have far less energy compared to the sound waves so they're super quiet and traveling at the speed of light. The light that hits one of these brilliant waves is going to be bent round the lens and will reflect back to the detector. In this way, the differences in frequencies could be measured and used to produce an array of extremely sensitive instruments.

Acousto-optics Devices are utilized in many applications including space vehicles. Some of the most common items in this field include radar systems, sonar, and ultrasound guns. The technology utilized in these devices allows them to detect differences in frequencies. They could also assess the acoustic properties of objects. Acoustic wave systems are also utilized in medical and dental practices. In dental practices, such systems are employed for teeth exams. Some dental hygienists use them for x-rays as well. These devices enable the dental professional to see within a patient's mouth without making direct visual contact. They're also used to hear the oral cavities to determine gum problems.
