We proposed a new incoherent optical frequency selection method called two-pack frequency-selective (TPFS) incoherent holography, which compresses two on-axis holograms into a single multiplexed on-axis hologram without loss of magnification and resolution. The spectrum we want to reconstruct is intercepted by multiple confounding correlation terms in the spatial frequency domain. The background bias term and conjugate term can be effectively suppressed. This work is the first to attempt a multiplexed reconstruction in the field of incoherent light. Experiment results highlight the potential of the proposed method in several areas, such as compressed holography and extended field of view imaging.

我们提出了一种新的非相干光学频率选择方法，称为双包频率选择（TPFS）非相干全息术，它将两个轴上全息图压缩成一个多路复用轴上全息图，而不会损失放大率和分辨率。我们要重建的频谱被空间频域中的多个混杂相关项截获。可以有效抑制背景偏置项和共轭项。这项工作是第一个尝试在非相干光领域进行多路复用重建的工作。实验结果突出了该方法在多个领域的潜力，例如压缩全息术和扩展视场成像。
