摘要

A refractive-index distribution measuring method includes the steps of measuring a transmitted wavefront of an object, determining a first refractive index distribution of the object based on a measurement result of the transmitted wavefront, determining a third refractive index distribution in a transmission direction of light of the transmitted wavefront based on information related to a second refractive index distribution of the object, and calculating a three-dimensional refractive index distribution of the object based on the first refractive index distribution and the third refractive index distribution.
