Multiple view projection holography is a method to obtain a digital hologram by recording different views of a 3D scene with a conventional digital camera. Those views are digitally manipulated in order to create the digital hologram. The method requires a simple setup and operates under white light illuminating conditions. The multiple views are often generated by a camera translation, which usually involves a scanning effort. In this work we apply a compressive sensing approach to the multiple view projection holography acquisition process and demonstrate that the 3D scene can be accurately reconstructed from the highly subsampled generated Fourier hologram. It is also shown that the compressive sensing approach, combined with an appropriate system model, yields improved sectioning of the planes of different depths.
多视角投影全息术是一种通过使用传统数码相机记录三维场景的不同视角来获取数字全息图的方法。这些视角经过数字处理以创建数字全息图。该方法所需的设置简单，且在白光照明条件下即可运行。多个视角通常由相机平移生成，这通常需要进行扫描工作。在这项工作中，我们将压缩感知方法应用于多视角投影全息术的采集过程，并证明可以从高度欠采样生成的傅里叶全息图中准确重建三维场景。研究还表明，压缩感知方法与适当的系统模型相结合，可改善不同深度平面的切片效果。
