摘　　要：针对传统测量方法不能同时实现功能性梯度材料外部三维轮廓测量和内部三维结构测量的缺陷,提出了基于数字全息层析的三维测量技术。以单模光纤作为实验样本,采用基于数字全息层析的三维测量技术对其进行分析。实验结果表明,基于数字全息层析技术的三维结构测量方法能很好地实现功能性梯度材料等一些透明物体的三维轮廓测量和内部三维结构测量。The traditional measurement methods can not simultaneously measure the external 3-D proifle and internal 3-D structure of functional gradient materials. In this paper, the 3-D measurement technique based on digital holographic tomography is proposed, and is used to analyze a single-mode ifber as an experimental sample. Experimental results show that the digital holography tomography can well achieve the external 3-D proifle measurement and internal 3-D structure measurement of functional gradient materials and other transparent objects.
