The principle of unconventional holography, called coherence holography, is proposed and experimentally demonstrated for the first time. An object recorded in a hologram is reconstructed as the three-dimensional distribution of a complex spatial coherence function, rather than as the complex amplitude distribution of the optical field itself that usually represents the reconstructed image in conventional holography. A simple optical geometry for the direct visualization of the reconstructed coherence image is proposed, along with the experimental results validating the proposed principle. Coherence holography is shown to be applicable to optical coherence tomography and profilometry.
首次提出并通过实验证明了一种非传统全息术原理，即相干全息术。全息图中记录的物体被重建为复空间相干函数的三维分布，而不是像传统全息术中通常表示重建图像的光场复振幅分布。提出了一种用于直接可视化重建相干图像的简单光学结构，以及验证所提原理的实验结果。结果表明，相干全息术适用于光学相干断层扫描和轮廓测量。
