ultrasonic detection

Ultrasonic detection uses high-frequency sound waves, beyond human hearing, to locate and measure objects or distances. A device emits ultrasonic waves that bounce off objects and return as echoes. By measuring the time it takes for the echoes to return, the device calculates how far away the object is. This technology is commonly used in various fields like medical imaging, automotive parking sensors, and industrial measurement to detect, map, or analyze objects accurately without physical contact.
