摘要

为了减少傅里叶单像素成像（FSPI）相移模式的数量，我们提出了一种非相移FSPI方法。在这种方法中，我们只使用0相移模式分别重建图像的上下半部分，然后将它们拼接在一起形成完整的图像。此外，采用基于乘法器交替方向法的图像补绘方法对拼接痕迹进行擦除。所提出的非相移FSPI的成像质量与多步FSPI相似。仿真和实验结果验证了该方法的有效性。

Non-phase-shift Fourier single-pixel imaging with conjugate symmetry of the Fourier spectrum and ADMM-based image inpainting.

To decrease the number of phase-shift patterns of Fourier single-pixel imaging (FSPI), we present a non-phase-shift FSPI method. In this method, we use only the 0 phase-shift patterns to reconstruct the top and bottom halves of the image separately and then stitch them together to form a complete image. In addition, an image inpainting method based on the alternating direction method of multipliers is adopted to erase the stitching mark. The imaging quality of the proposed non-phase-shift FSPI is similar to multiple-step FSPI. Simulation and experimental results validate the effectiveness of the proposed method.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
