Fresnel incoherent correlation holography (FINCH) was proposed to break the barrier of spatial incoherent digital holographic imaging and show the potential of super-resolution imaging preferences. We developed FINCH as a compressive sensing modality and reconstruction procedure as an inverse problem in order to realize 3D tomographic imaging. Improved axial resolution is obtained via compressive reconstruction. Reconstruction guarantees and accuracy of the proposed method are discussed. Compared with the real-valued signal operation, the signal-to-noise ratio of the results is increased when reconstructing from the complex-valued hologram obtained from the FINCH system.
菲涅耳非相干相关全息术（FINCH）被提出来打破空间非相干数字全息成像的障碍，并展现出超分辨率成像偏好的潜力。我们将FINCH开发为一种压缩感知模式，并将重建过程作为一个反问题，以实现三维层析成像。通过压缩重建可获得更高的轴向分辨率。文中讨论了所提方法的重建保证和准确性。与实值信号运算相比，从FINCH系统获得的复值全息图进行重建时，结果的信噪比会提高。
