摘要： 最近建立一套用干晶体三维实时观察的装置，主要分为光学观察部分，晶体生长部分，结果处理部分．采用二目观察法记录晶体生长和流体运动．设计并制造适于Ｂｒｉｄｇｍａｎ法晶体生长的生长炉和坩埚．初步观察到ＮａＮＯ３晶体的固液界面形貌，并通过图像处理软件还原为三维真实图像．

Abstract: A three-dimensional real-time observation instrument was developed, which was con- sisted of crystal part, optic observation part, and result analysis part. The crystal growth and flow movement was observed by the two-eye observation method. A new growth furnace and crucible, being suitable for Bridgman method crystal growth, was developed. The solidliquid interface of NaNO3 was visualized. At last the image visualized was synthesized into three-dimensional image by a processing software.

Key words: melt crystal growth, three-dimensional observation, image processing
