Abstract : A quantized version of a continuous spiral phase ﬁlter with unitary topological charge, here denominated multi-step spiral phase ﬁlter (MSSPF), is proposed to extract phase from rotated spiral interferograms. Spiral interferograms are usually obtained from phase objects by registering the interference of its vortex ﬁltered complex amplitude with a reference complex amplitude. Furthermore, it is shown that this novel technique can be applied without further modiﬁcations for phase contrast measurement. Experimental results show similar performance of this phase extraction technique implemented in a Mach-Zender interferometer.
