In this work compressive holography (CH) with multiple projection tomography is applied to solve the inverse ill-posed problem of reconstruction of three-dimensional (3D) objects with high axial accuracy. To visualize the 3D shape, we propose digital tomographic CH, where projections from more than one direction, as in tomographic imaging, can be employed, so that a 3D shape with improved axial resolution can be reconstructed. Also, we propose possible schemes for shadow elimination when the same object is illuminated at multiple angles using a single illuminating beam and using a single CCD. Finally, we adapt CH designed for a Gabor-type setup to a reflective geometry and apply the technique to reflective objects.
在这项工作中,采用具有多重投影层析成像的压缩全息术(CH)来解决高轴向精度的三维(3D)物体重建的逆不适定问题。为了可视化3D形状,我们提出了数字层析CH,其中可以像在层析成像中那样采用来自多个方向的投影,从而能够重建具有更高轴向分辨率的3D形状。此外,我们还提出了可能的方案,用于在使用单个照明光束和单个电荷耦合器件(CCD)以多个角度照射同一物体时消除阴影。最后,我们将为加博尔型设置设计的CH应用于反射几何结构,并将该技术应用于反射物体。
