Abstract

It is described theoretically and experimentally that the degradation produced on a double-beam interferogram by the imperfection of the optical elements is eliminated by using the Moiré technique. In this method the information of the phase object is obtained as the Moiré pattern by superposing the interferograms with and without the object through the imperfect optical system.
