New paper in Optics Letters with a self-interference technique to retrieve the phase of diffraction gratings
Our last paper published in Optics Letters entitled Retrieving the phase of diffraction orders generated with tailored gratings, presents a self-interferometric technique based on a liquid-crystal SLM, useful to measure the phase content of diffraction gratings.
A Fourier transform optical setup is converted into a polarization common-path interferometer by simply rotating a polarizer. Then, this configuration allows a phase-shifting interferometry algorithm to be applied to retrieve the phase of the diffraction orders.
The paper has been highlighted as Editor’s pick.
