英文摘要：

The optical interferometrie method can be used to monitor the optical path change of the media through which the light beam passed. By analyzing the information of interference fringes obtained during the crystal growth from solution, the parameters related with the optical path difference, such as the crystal growth rate, the concentration distribution around the crystals, and the temperature profile, can be derived. These parameters are important for understanding the mechanism of the processes of the crystallization. Therefore the interferometric method has become a powerful tool for studying the crystal growth. In this paper, the measurement principle and recent applications of the interferometric method in the field of crystal growth are reviewed, and the future trends in this field are discussed.
