[0022] A measuring instrument is used to measure the crystal orientation of the crystal material. The measuring instrument includes a rotating table assembly 18, an ultrasonic probe 24, an orientation head 20, a motor 27, an XRD probe and a display (not shown).
[0023] Such as figure 2 , Fix the crystal in the fixture of the rotating table assembly 18, use the ultrasonic probe 24 to set a virtual plane for measurement, the orienting head 20 moves downwards, and under the detection of the ultrasonic probe 24, to the set virtual plane The plane stops, and the rotating worktable assembly 18 is driven by the motor 27 to rotate 360 degrees, the rotation accuracy is ≤30", and the XRD detector is used for scanning. According to the characteristics of the crystal, it will be displayed on the display as image 3 The waveform of the schematic shown, image 3 The X axis is the position angle of the rotating worktable, and the Y axis is the angle value measured by the crystal orientation a...
