Abstract

This paper presents a digital off-axis holographic tomography based on only three off-axis holograms. In experiment, a section of optical fiber is used to be the tested object. It has parabola refraction index characteristic and symmetry 3D structure. The results show that our presented method is valid. And it can be applied to measure the refraction index of some functional materials or 3D structure of phase objects.
