摘要：

We report a technique for measuring the three-dimensional variation of refractive indices in a microscopic sample. The technique is an adaptation of optical computed tomography and is effective in measuring the three-dimensional refractive-index distribution of a nonabsorbing microscopic sample. Our report also includes a discussion of the conditions for the unambiguous application of the technique as well as results of experiments conducted with Aspergillus oryzae (commonly known as green mold) as the sample.
