Coded imaging under natural light via incoherent digital holography and lensless optics

This study presents a method for single-shot, natural-light, full-color motion-picture holography. Incoherent digital holography (IDH) actively exploits the wave nature of light to capture complex amplitude, enabling highfidelity 3D reconstruction and digital refocusing. We report on a portable holographic camera system equipped with a birefringent dual-focus lens and a polarization color image sensor. This architecture realizes a robust common-path phase-shifting interferometer capable of single-shot acquisition. We experimentally demonstrate the recording of 3D full-color videos of moving subjects and outdoor scenes illuminated solely by spatially and temporally incoherent light.
