这封信提出了一个在线数字全息系统，可以提供完整的振幅和相位重建没有任何参考波，与一个单一的记录全息图。这一主要能力是通过使用由纯空间相位调制产生的几个物波之间的相干混合来获得的。缩放参数允许我们在不进行任何解缠的情况下重建相位。通过实验结果证明了该方法提供定量相衬测量和数值重聚焦的能力。
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.
