A new kind of interferometer for testing any unit magnification optical system is described. The method utilizes diffraction beam splitting and involves the use of two identical Fresnel zone plates, one by the side of the other. The interference patterns obtained are easy to interpret because the fringes are the loci of equal optical path difference of the wavefront under test with respect to a reference sphere.
