Abstract

We present a novel method for recovering the whole 3D structure of a nonuniform refractive space. The refractive space may consist of a single nonuniform refractive medium such as heated air or multiple refractive media with uniform or nonuniform refractive indices. Unlike most existing methods for recovering transparent objects, our method does not have a limitation on the number of light refractions. Furthermore, our method can recover both gradual and abrupt changes in the refractive index in the space. For recovering the whole 3D structure of a nonuniform refractive space, we combine the ray equation in geometric optics with a sparse estimation of the 3D distribution. Testing showed that the proposed method can efficiently estimate the time varying 3D distribution of the refractive index of heated air.
