Title: (EN) SYSTEMS AND METHODS FOR REAL-TIME LASER DOPPLER IMAGING
(ZH) 实时激光多普勒成像的系统和方法
Abstract: front page image
(EN) Disclosed methods and systems may be operable to obtain non-contact diagnostic information about movements of scattering objects such as fluids in subsurface vasculature in tissue. As an example, a method may include causing a light source to illuminate the tissue with at least a first portion of the emitted light and illuminate an optical modulator with at least a second portion of the emitted light. The second portion of the emitted light may be modulated by the optical modulator. An offset source is configured to provide an offset frequency signal. An image sensor may receive optical information from the sample. A heterodyne signal based on the reference frequency signal and the offset frequency signal may be used as a gain input of each detector element of the image sensor. Based on the received information, a movement of a portion of the sample may be determined.
(ZH) 公开的方法和系统可以操作为获得关于诸如组织中表面下脉管中的流体的散射物体的运动的非接触式诊断信息。作为示例,方法可以包含引起光源来用发射的光的至少第一部分照明组织并且用发射的光的至少第二部分照明光学调制器。可以由光学调制器来调制发射的光的第二部分。偏移源配置为提供偏移频率信号。图像传感器可以从样品接收光学信息。基于参考频率信号和偏移频率信号的外差信号可以用作图像传感器的每一个检测器元件的增益输入。基于接收的信息,可以确定样品的部分的运动。
