我们提出了单次非相干数字全息术，其中采用了单路径同轴结构和相移干涉计量术。利用光波的空分复用和偏振态实现了并行相移全息。构造了一种平行相移的单光路装置，以便于以紧凑的系统轻松地捕获非相干全息图。使用平行相移获得了没有不需要的衍射波的瞬时和三维(3D)物体图像。通过对透明物体和反射物体的实验验证了该方法的有效性。
We propose single-shot incoherent digital holography in which a single-path in-line configuration and phase-shifting interferometry are adopted. Space-division multiplexing and polarization states of the waves are utilized to implement parallel phase-shifting holography. A single-path setup in parallel phase-shifting is constructed to capture an incoherent hologram easily with a compact system. An instantaneous and three-dimensional (3D) object image is obtained without undesired diffraction waves using parallel phase-shifting. The validity of the proposed technique is experimentally demonstrated for both transparent and reflective objects.
