Real-time digital holographic microscopy observable in multi-view and multi-resolution

在这项研究中，我们提出了一种多视角、多分辨率的DHM观测值。利用移位菲涅耳衍射代替菲涅耳衍射，DHM可以获得任意分辨率、深度和位置的多个重建图像。基于菲涅耳衍射的移位菲涅耳衍射法可以计算出全息图和再现像之间不同采样间隔的再现像，以及偏离传播轴的移位。此外，我们使用了四个图形处理单元(GPU)芯片来实时观察一张全息图中的四个重建图像。

In this study, we propose a DHM observable in multi-view and multi-resolution. The DHM can obtain multiple reconstructed images with arbitrary resolution, depths and positions, using shifted- Fresnel diffraction, instead of Fresnel diffraction. Shifted-Fresnel diffraction based on Fresnel diffraction can calculate a reconstructed image with different sampling spacings between the hologram and the reconstructed image, as well as a shift away from the propagation axis. In addition, we used four graphics processing unit (GPU) chips in order to observe four reconstructed images in real-time from one hologram.
