    • Methods, systems, and devices are disclosed for implementing Doppler optical coherence tomography and microangiography imaging. In one aspect, a device for optically measuring a sample includes a swept light source to produce an input beam of coherent light for optically probing a target area of a sample, a waveguide to guide the input beam in two independent propagation modes, an optical probe to reflect a first propagation mode back to the waveguide and to direct a second propagation mode to the sample and to overlap the reflection from the sample with the first propagation mode, a differential delay controller to produce variable relative phase delays between the first propagation mode and the second propagation mode, a detection module to combine the first propagation mode and the second propagation mode and to extract information of the sample, and a processing unit to process the information to produce optical images.
    • 公开了用于实现多普勒光学相干断层扫描和微血管造影成像的方法,系统和装置。 在一个方面,用于光学测量样品的装置包括扫描光源,以产生用于光学探测样品的目标区域的相干光的输入光束,以两个独立传播模式引导输入光束的波导,光学探针 将第一传播模式反射回波导并且将第二传播模式引导到样本并且使来自样本的反射与第一传播模式重叠;差分延迟控制器,用于在第一传播模式与第一传播模式之间产生可变的相对相位延迟; 第二传播模式,组合第一传播模式和第二传播模式并提取样本信息的检测模块,以及处理该信息以产生光学图像的处理单元。
