    • A control module is configured to receive one or more input signals. An optical selection network includes a plurality of optical input ports configured to receive respective optical waves at an operative wavelength, and at least one optical output port configured to provide an optical wave at the optical wavelength. The optical selection network is configured to receive one or more control signals from the control module, and in response to the control signals, provide a high transmission path for the operative wavelength from an optical input port, determined by the input signals, to the optical output port at a predetermined time with respect to a time reference in at least one of the input signals, and provide a low transmission path for the operative wavelength from each of a plurality of optical input ports, determined by the input signals, to the optical output port at the predetermined time.

    • Phase-conjugate optical coherence tomography (PC-OCT) methods and apparatus. PC-OCT may be employed as a three-dimensional imaging technique of interest for biomedical and other imaging applications. It shares much of the source and detection convenience of conventional OCT employing classical light sources, which is in clinical use in ophthalmology and is being developed for a variety of endoscopic optical biopsy instruments. PC-OCT offers a two-fold improvement in axial resolution and immunity to group velocity dispersion, when compared with conventional OCT, that is available from quantum optical coherence tomography (Q-OCT). PC-OCT does this without Q-OCT's need for a non-classical light source and the attendant requirement of photon-coincidence counting detection. Thus, in comparison with Q-OCT, PC-OCT is capable of producing images in measurement times similar to those of conventional OCT.
    • 相位共轭光学相干断层扫描(PC-OCT)方法和装置。 PC-OCT可用作用于生物医学和其它成像应用的三维成像技术。 它共享了传统OCT采用古典光源的大部分来源和检测便利性,这种光源在眼科临床应用中正在开发用于各种内窥镜光学活检仪器。 与常规OCT相比,PC-OCT与轴向分辨率和群体速度色散的抗扰度提供了两倍的改进,可从量子光学相干断层扫描(Q-OCT)获得。 PC-OCT在没有Q-OCT需要非经典光源的情况下以及伴随的光子重合计数检测要求。 因此,与Q-OCT相比,PC-OCT能够在与常规OCT相似的测量时间内产生图像。
