This Letter presents an in-line digital holographic system that can provide full amplitude and phase reconstruction without any reference wave, with a single recorded hologram. This major capability is obtained by using a coherent mixing between several object waves generated by a pure spatial phase modulation. A scaling parameter permits us to reconstruct the phase without any unwrapping. The capability of the method to provide quantitative phase contrast measurement and numerical refocusing is demonstrated through experimental results.
