Paper Abstract

We propose single-shot incoherent digital holography using parallel-phase shifting radial shearing interferometry. The object wave from an incoherently illuminated or self-luminous object is Fourier transformed, and enters a parallel phase-shifting radial shearing interferometer. Then, the radially sheared two object waves combines and the hologram whose phases are relatively shifted in every 2x2 pixels of the image sensor are generated. By applying parallel phaseshifting interferometry to the hologram, we obtain the amplitude and the phase of the complex spatial coherence function of the object wave. Then, the complex amplitude distribution of the object wave at arbitrary depth is calculated from the function. We applied the proposed technique to the three-dimensional imaging of two LEDs and experimentally demonstrated the proposed technique.
