In this Letter, we propose spatially incoherent multiwavelength three-dimensional (3D) microscopy that exploits holographic multiplexing and is based on computational coherent superposition (CCS). The proposed microscopy generates spatially incoherent wavelength-multiplexed self-interference holograms with a multiband-pass filter and spatially and temporally incoherent light diffracted from specimens. Selective extractions of 3D spatial information at multiple wavelengths from the holograms are realized using the CCS scheme. We constructed fully mechanical-motion-free holographic multiwavelength 3D microscopy systems and conducted experiments to demonstrate the microscopy.
在本信函中，我们提出了一种利用全息复用且基于计算相干叠加（CCS）的空间非相干多波长三维（3D）显微镜技术。所提出的显微镜技术利用多带通滤波器和从样本衍射的空间和时间非相干光，生成空间非相干波长复用自干涉全息图。使用CCS方案可从全息图中选择性提取多个波长下的三维空间信息。我们构建了完全无机械运动的全息多波长3D显微镜系统，并进行了实验以证明该显微镜技术。
