论文摘要
光学相干断层扫描（OCT）是一种关键的3D成像技术，可为生物形象提供微米尺度的深度分辨率。由于检测电子的冲动响应，该分辨率实质上超过了它在光检测和范围（LIDAR）中通常实现的（LIDAR）。但是，例如，机械运动引起的激光雷德场景缺乏连贯性，使OCT几乎不可行。在这里，我们提出了一种量子干扰启发的大雨的方法，该方法可以实现OCT深度分辨率，而无需高水平的稳定性。我们以70μm的有效脉冲响应的有效脉冲响应展示了深度成像功能，从而使范围和多种反射能够以比常规激光雷达方法更高的分辨率来识别。这种增强的分辨率为3D面部识别中的LiDAR提供了途径，以及小型特征检测/跟踪，并增强了更复杂的飞行时间方法的功能，例如通过晦涩的成像和非线视觉成像进行成像。
Optical Coherence Tomography (OCT) is a key 3D imaging technology that provides micron scale depth resolution for bio-imaging. This resolution substantially surpasses what it typically achieved in Light Detection and Ranging (LiDAR) which is often limited to the millimetre scale due to the impulse response of the detection electronics. However, the lack of coherence in LiDAR scenes, arising from mechanical motion for example, make OCT practically infeasible. Here we present a quantum interference inspired approach to LiDAR which achieves OCT depth resolutions without the need for high levels of stability. We demonstrate depth imaging capabilities with an effective impulse response of 70 μm, thereby allowing ranging and multiple reflections to be discerned with much higher resolution than conventional LiDAR approaches. This enhanced resolution opens up avenues for LiDAR in 3D facial recognition, and small feature detection/tracking as well as enhancing the capabilities of more complex time-of-flight methods such as imaging through obscurants and non-line-of-sight imaging.
