Abstract

We propose a new holographic method for investigating liquid and gas media which permits determining the absolute value of the difference of the refractive indices of the reference medium and of the medium under study by one interferogram. The light wave passing sequentially through the reference medium and the medium under study is reflected from the object with the known form of the diffusely reflecting surface. As a result of reconstruction of the two-exposure hologram obtained, as interference pattern is formed, the spatial frequencies are proportional to the difference of the refractive indices of the reference medium and the medium under study.
