Interference image acquiring device and method for acquiring interference image

An interference image acquisition apparatus includes a light source, a beam splitter, a second reflection mirror, an imager, and a first reflection mirror. A cell is placed on one side of a transparent material, and the first reflection mirror is placed on the other side of the transparent material. In a two-beam interferometer, an optical path difference between an optical path length of a first light beam reflected by the first reflection mirror and an optical path length of a second light beam reflected by the second reflection mirror is set to a coherence length of light output from the light source or less. The imager acquires an interference image in a state in which the cell is placed at a position conjugate to an imaging plane in a first optical system between the imaging plane and the first reflection mirror.
