提出了一种单次非相干全息成像技术，该技术采用自干涉非相干数字全息（SIDH），光学结构中平面镜略有倾斜。有限的时间相干长度的照明导致该系统的导星全息图有一个椭圆环形状的高斯包络。实验结果表明，用导星全息图进行互相关再现，比通常的传播方法获得了更好的再现质量。实验上，我们验证了全息图和三维重建可以实现非相干与建议的单次拍摄离轴SIDH。
We propose a single-shot incoherent holographic imaging technique that adopts self-interference incoherent digital holography (SIDH) with slight tilt of the plane mirror in the optical configuration. The limited temporal coherence length of the illumination leads the guide-star hologram of the proposed system to have a Gaussian envelope of elliptical ring shape. The observation shows that the reconstruction by cross correlation with the guide-star hologram achieves better quality than the usual propagation methods. Experimentally, we verify that the hologram and 3D reconstruction can be implemented incoherently with the proposed single-shot off-axis SIDH.
