论文摘要
量子光学相干断层扫描（Q-OCT）是光学相干断层扫描（OCT）的非经典对应物 - 一种基于白光干扰法的高分辨率3D成像技术。由于Q-OCT使用频率键入光子对的来源，不仅轴向分辨率不受干涉仪中分散不匹配影响的轴向分辨率，而且还可以固有地改善了两个平方根的系数。不幸的是，Q-OCT的实际应用会受到图像制作的人工制品和缓慢的获取时间的阻碍。在这里，我们对没有这些问题的新方法进行了理论分析：具有关节频谱检测的Q-OCT（JS-Q-OCT）。基于像标准Q-OCT配置一样，基于光子对重合检测，它也可以辨别每个光子对通过其波长。我们表明，有关对象的内部结构的所有信息均在关节频谱中编码，并且可以通过傅立叶变换轻松检索。无需深度扫描，使我们的技术可能比标准Q-OCT快。最后，我们表明，关节频谱中可用的数据可以删除伪影并讨论这样做的前瞻性算法。
Quantum Optical Coherence Tomography (Q-OCT) is the non-classical counterpart of Optical Coherence Tomography (OCT) - a high-resolution 3D imaging technique based on white-light interferometry. Because Q-OCT uses a source of frequency-entangled photon pairs, not only is the axial resolution not affected by dispersion mismatch in the interferometer, but is also inherently improved by a factor of square root of two. Unfortunately, practical applications of Q-OCT are hindered by image-scrambling artefacts and slow acquisition times. Here, we present a theoretical analysis of a novel approach that is free of these problems: Q-OCT with joint spectrum detection (JS-Q-OCT). Based on a photon pair coincidence detection as in the standard Q-OCT configuration, it also discerns, each photon pair by their wavelength. We show that all the information about the internal structures of the object is encoded in the joint spectrum and can be easily retrieved through Fourier transformation. No depth scanning is required, making our technique potentially faster than standard Q-OCT. Finally, we show that the data available in the joint spectrum enables artefact removal and discuss prospective algorithms for doing so.
