We present a new configuration for superresolution (SR) as well as for field-of-view (FOV) extension in a digital holography concept based on random movement of sparse metallic particles. In the SR configuration, the particles are in proximity to the recorded object, while in the FOV configuration, the particles are in proximity to the hologram plane. The particles' movement encodes the high spatial features in the plane of their movement. This high-resolution information can later be decoded by proper numerical postprocessing that either remedies the resolution limitations in the object plane (or the limited NA of the lens) or extends the FOV in the object plane.
我们提出了一种新的配置，用于数字全息术概念中的超分辨率 (SR) 和视场 (FOV) 扩展，该配置基于稀疏金属粒子的随机运动。在 SR 配置中，粒子靠近记录的物体，而在 FOV 配置中，粒子靠近全息图平面。粒子的运动编码了其运动平面中的高空间特征。该高分辨率信息可以通过适当的数值后处理来解码，该后处理可以纠正物体平面中的分辨率限制（或透镜的有限 NA），或者扩展物体平面中的 FOV。
