“…Phase-shifting interferometry (PSI) is a very efficient and accurate classical technique, where a phase distribution is retrieved from a sequence of phase-shifted interferograms [11]. Although the most common device for phase shifting is a piezoelectric transducer, LC retarders have also been extensively used [12,13]. LC-SLMs have been also exploited to build several interferometric and holographic systems [14].…”

In this work we apply a phase-shifting interferometry (PSI) to evaluate the reconstruction of complex-valued holograms displayed onto a phase-only spatial light modulator (SLM). The interferometer is vibration-free since it uses a common-path polarization arrangement based on the SLM itself, which is used simultaneously to display the hologram and to apply the phase-shifting values. The change from the hologram display configuration to the interferometer configuration involves only a rotation of a polarizer. The continuous phase modulation provided by the SLM allows using PSI with arbitrary phase bias values. Several examples are demonstrated by generating different combinations of modes with an efficient on-axis hologram encoding technique.

“…On the other hand, liquid crystal retarders are very useful devices in interferometry. In phase-shifting interferometry (PSI) they are employed to impart controlled phase bias to the interferograms to retrieve the target phase function [2]. LC-SLMs can be used to display spatially retardance functions that provide a common-path interferometric arrangement [3].…”

We present a technique that combines an encoding method to display complex-valued holograms onto a phase-only spatial light modulator (SLM) with a phase-shifting interferometric (PSI) technique for experimentally evaluating the generated complex-valued optical fields. We demonstrate an efficient common-path polarization interferometer based on the SLM itself, not requiring any external additional element. The same setup can be used to simultaneously display the complex hologram and to apply the phase-shifting values required to retrieve the phase distribution of the optical field. A simple rotation of a polarizer allows to change from the intensity configuration to the interferometer configuration.
