The invention discloses a detection method of a seed rod shaking detection device and a crystal growth method. The detection method includes the steps of: controlling the imager to image the seed rod to obtain an image sequence corresponding to the seed rod; The images in the image sequence are images within one vibration period of the seed rod, and the image sequence includes a first image and a second image; according to the image sequence, the vibration information of the seed rod is determined. Because the image sequence corresponding to the seed rod is obtained through the imager, the image sequence includes the first image and the second image, and the shaking information of the seed rod is obtained according to the image sequence, so as to detect the shaking of the seed rod during the crystal growth process.
Description
technical field [0001] The invention relates to the technical field of shake detection, in particular to a detection method of a seed rod shake detection device and a crystal growth method. Background technique [0002] In the prior art, when preparing single crystals such as gallium oxide, raw materials such as gallium oxide are first melted, and then a seed rod loaded with a seed crystal is used to pull from the surface of the melt to obtain a single crystal. When preparing gallium oxide single crystals, the seed rod is prone to shaking, resulting in low crystal quality. The vibration of the seed rod during the crystal growth process cannot be detected in the prior art. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a detection method of a seed rod shake detection device and a crystal growth method in view of the above-mentioned defe...
