Abstract: We present a novel interferometric method for testing refractive conical lenses. The optical configuration requires only two mutually coherent plane wave fronts transmitted through the optical component under test. It can be interpreted as reversal shear interferometric technique. The method can also be considered as an interferometric fringe projection method. Measurements have bean realized for determing the base angle of the refractive cone under test and the aberrations introduced.
