Method for measuring refraction angle of ultrasonic probe

The invention discloses a method for measuring the refraction angle of an ultrasonic probe, and the method comprises the steps: S100, employing a single-probe detection mode, enabling a to-be-detectedprobe to face one side, with scales, of a test block, placing the to-be-detected probe at an approximate central position of a rectangular surface of the test block for scanning, and maintaining theprobe and the test block to be relatively static after the highest reflection wave is found; and S200, adopting a serial scanning mode, wherein the serial probe scans the cylindrical surface of the test block to find the highest wave, and at the moment, the scale value of the angle on the test block corresponding to the center line of the serial probe is the value of the refraction angle of the probe. The measuring method comprises the following steps: direct waves of a to-be-detected probe are directly received through a serial probe; and the value of the refraction angle of the probe is directly read on the test bloc
