Abstract

A holographic method of determining the refractive index of liquid and gaseous media by optical computing is proposed. In the cell, in which the reference and investigated media are placed sequentially, there is an object with the known shape of the diffusely reflecting surface. As a result of the two-exposure hologram reconstruction, an interference pattern containing information about the difference of the refractive indices of the reference and investigated media is formed.
