Abstract: This work demonstrates the impact of sampling basis resolution on Single Pixel Imaging’s ability to accurately measure the amplitude and phase of an arbitrary complex light field. We observe that phase crosstalk occurs in the reconstructed amplitude when the sampling basis is coarser than the underlying phase distribution. To investigate this phenomenon, a spatial light modulator is employed to prepare the complex field—comprising both amplitude and phase—utilizing a phase-only hologram. The field is then sampled at various resolutions using the Hadamard basis on the same SLM with interferometric Single Pixel Imaging. Measurement of the field takes place on a single point through 3-step interferometry and a Mach-Zehnder interferometer. While the phase is correctly reconstructed for each resolution, our findings reveal distinctive attributes of the phase distribution in the reconstructed amplitude for coarser sampling resolutions.
