量子光学相干层析成像（Q-OCT）提供了一种色散抵消轴向成像方法，但其实际应用受到光源的弱点和图像中的伪影的限制。最近的一项研究使用啁啾脉冲干涉测量（CPI）已经证明了色散消除和无伪影OCT与经典系统；然而，去除伪影后，不需要的背景信号仍然存在。在这里，我们提出了一种经典光学方法来实现色散抵消、无伪影和无背景的OCT。我们采用了一种时间反转系统，用于具有变换限制输入激光脉冲的Q-OCT，以实现经典系统的色散抵消OCT。我们还介绍了一种减法方法来去除伪影和背景信号。通过这些方法，我们实验证明了消色散、无伪影和无背景的覆盖玻璃轴向成像和硬币表面的横截面成像。(C) 2016年美国光学学会
Quantum-optical coherence tomography (Q-OCT) provides a dispersion-canceled axial-imaging method, but its practical use is limited by the weakness of the light source and by artifacts in the images. A recent study using chirped-pulse interferometry (CPI) has demonstrated dispersion-canceled and artifact-free OCT with a classical system; however, unwanted background signals still remain after removing the artifacts. Here, we propose a classical optical method that realizes dispersion-canceled, artifact-free, and background-free OCT. We employ a time-reversed system for Q-OCT with transform-limited input laser pulses to achieve dispersion-canceled OCT with a classical system. We have also introduced a subtraction method to remove artifacts and background signals. With these methods, we experimentally demonstrated dispersion-canceled, artifact-free, and background-free axial imaging of a coverglass and cross-sectional imaging of the surface of a coin.
