X-ray is a technology that uses X-rays to scan objects. After scanning an object with X-rays, we can obtain an image of the object's internal structure. We can then use this image to analyze the object, such as detecting defects in the object or identifying objects inside the object.
This document describes a device for detecting and measuring ultrasonic signals. The device includes an ultrasonic transmitter, an ultrasonic receiver, and a digital signal processor. The ultrasonic transmitter emits ultrasonic signals, and the ultrasonic receiver receives the reflected ultrasonic signals. The digital signal processor processes the received ultrasonic signals and generates measurement results.
