A new tomographic method for the measurement of three-dimensional refractive-index fields of transparent media, which we call holographic coherence tomography and which combines double-exposure holographic interferometry with the detecting style of optical coherence tomography, has been developed. The three-dimensional refractive-index field can be achieved with a confocal lens system by continual longitudinal and horizontal scanning of the holographic reconstruction image.
