Tomographic reconstruction techniques used to obtain three-dimensional refractive index fields from interferometric data all assume that the correct fringe number has been assigned. In confined fields or where the imaging beam is smaller than the object field, only relative fringe numbers can be determined from the interferogram because no reference (undisturbed) region is visible. An algorithm that can be applied to iterative reconstruction techniques is described that permits the quantitative reconstruction of three-dimensional fields by using only relative fringe numbers provided that a priori data are supplied. This method is applied to an existing reconstruction technique and is demonstrated by using simulated interferometric data.
用于从干涉数据中获取三维折射率场的层析重建技术都假定已经分配了正确的条纹数。在受限场或成像光束小于物场的情况下，由于看不到参考（未受干扰）区域，只能从干涉图中确定相对条纹数。本文描述了一种可应用于迭代重建技术的算法，该算法允许在提供先验数据的情况下，仅使用相对条纹数对三维场进行定量重建。该方法应用于现有的重建技术，并通过模拟干涉数据进行了验证。
