| 摘 要： | 介绍了一种新的重构三维折射率场的方法。该方法利用一个共焦检测系统对被测对象的像面全息干涉图进行三维扫描，并记录干涉强度，通过对强度数据的处理，可以重构出三维折射率场。这种方法原理简单，不需要进行多方向的全息干涉记录和复杂的重构过程。给出了初步的试验结果，证明该方法是可行的。 |

| Abstract: | A new technique for reconstructing three dimensional refractive index field was proposed, which utilized a confocal system to scan the reconstructed holographic interferogram of a measured object in three dimension, and the recorded interference intensity was processed to obtain three dimensional refractive index field. For this method, the mechanism is very simple, and the multidirectional holographic interferometric scan and complex reconstruction algorithm are not needed, also not interfere the measured field and is a non|intrusive measurement method. The priliminary experimental result was given to demonstrate the feasibility of this method. |
| Keywords: | holographic interferometry tomography refractive index confocal system |
