Abstract
We report a simple setup for two-step quadrature phase-shifting holography that could be useful and suitable for industrial applications. Only two on-axis holograms are captured with the system and a complex hologram is formed from the two holograms. Autocorrelation is used to quantify the quality of all the reconstructed images from the holograms. We have tested a transparent sample as well as a reflective sample to validate this simple setup.
